You could line the bottom of their drinking glass with pure sodium and set it next to a water pitcher....and wait for the fun to ensue!! It always gets a good laugh.

how about laxatives...that will set off a few chemical reactions !

KABOOM!
-
I remember being somewhat naughty at school & pinching a matchbox-sized piece of sodium from the chem lab. We had our own swimming pool at school & I chucked the sodium in during a gala. Although my fellow pupils were highly amused the teachers were none too pleased (to put it mildly). Oh I wish the cane had already been banned by that time!
-
The actual chemistry goes about like this:
Sodium reacts with water to form sodium hydroxide and hydrogen.
The reaction produces heat, causing the hydrogen to ignite and burn in the oxygen from the air.
Na (s) + H2O (l) --> Na+ (aq) + OH- (aq) + 1/2 H2 (g)
then
2 H2 (g) + O2 (g) --> 2 H2O
So you get a load of heat/light.

That's quite a lump of sodium.

thats a HUGE lump! How big was this kaboom?! Would have been better if it was potassium. Nothing more though, we dnt want people getting injured!

The kaboom was enormous & a fair few people got more than just a little wet.

I remember one involving different states of matter and food.
Fill a balloon with grape juice and freeze it (preferably so that it stays round, like floating in a shallow bowl of water in the freezer).
Get a bowl big enough to just swallow the grape juice ball and make a big batch of gelatin (lime green or something translucent). Just before it's completely firm, push the grape juice ice ball down into it so that it's completely surrounded by gelatin.
When you tip the gelatin out onto a plate, it will appear to have a second, purple bit of gelatin inside, but when you cut into it, the grape juice just gushes out.
Maybe not exploding sodium, but certainly something to get your guest's attention at a dinner party.
Thanks,

So how does one procure a lump of sodium ?....do you go to Sodium Blocks R Us ?...presumably I just can't waddle into my local chemist/pharmacist/drugstore/chemical dealer with a cheeky grin and ask for a chunk of sodium eh ?

http://www.thenakedscientists.com/forum/topic.asp?TOPIC_ID=1014
It's Francium. There was a discussion of this a little while ago, and I think the conclusion was that Francium, if you can get hold of it (which is tricky as it's radioactively unstable), would react pretty vigorously with water but possibly less so than Caesium (immediately above Francium in group I) as it's stabilised (or whatever) by relativistic effects.
-
Yup it's a shame you can't get hold of Francium [;)]. It's only made in a handful of atoms at a time. If you did somehow get a chunck of it, it would react strongly? So it would be a bit dangerous to say the least.
wOw the world spins?

[:D]I'm happy to have this webpage. I hope it would help me a lot.

I saw a pellet of sodium fizz like crazy before the hydrogen exploded ... the teacher dropped it into a bucket of water at our chemistry club; didn't expect the bang though.
My favourite chem prank is to put a few drops of indicator dye into one's beer or coffe, then wait for them to scream when they pee red or blue. Although phenolphthalein has some carcinogenic properties, a few drops is all that's required.

Too complicated. I just filled the sugar bowl with salt.

just a tiny jar or bottle with a little acid in and drop in a small amount of iron ferrous sulphide, (or sulphate, not really sure now) readilly available at any chemical outlet. inexpensive also. You may be able to obtain some from your chemistry class.
again, not sure if the fumes were toxic, but the acid definately will burn holes in your clothes and skin so take care when using it.
Chris, naa this was far worse than any madras methane production.

Ouch,
A practial joke doesn't hurt people.
Try to add some methylene blue solution to food in such a way that it can't be seen: a dark drink, or add crystals to a food where they don't stand out. It is available at pet stores as it is used in fish tanks to kill ick a fungus. The stuff is not considered poisonous, but don't go overboard as a few drops or crystals will do the trick.
Methylene blue is a dye and will stain the tongue and mouth blue for a day, and even more interesting (for men only, women don't watch) it turns their urine green...

i know quite a few of these:-
To make a paint bomb you simply need a metal paint can with a refastenable lid, a nice bright color paint (green, pink, purple, or some gross color is perfect!), and a quantity of dry ice. Place the paint in the can and then drop the dry ice in. Quicky place the top on and then run like hell! With some testing you can time this to a science. It depends on the ratio of dry ice to paint to the size of the can to how full it is. If you are really pissed off at someone, you could place it on their doorstep, knock on the door, and then run!! Paint will fly all over the place HAHAHA!!

I suspect this thread might qualify as "contributing to the delinquency of a minor."
In a lab I used to work in, my friend once painted the rims of all the coffee cups in the lunchroom with a nail polish that is designed to taste terrible.. supposed to deter nail biting. Anyway, the stuff was invisible on the ceramic cups and it didn't come off with washing. Everybody thought the coffee was terrible - so they brewed another pot, which was just as bad. Then they decided it must be the water and, sure enough, the water tasted terrible too. Of course, this was at an environmental testing lab, so there were plenty of experts around to theorize on what might be in the water and how to test for it, etc.

Here's what i can see as being the ultimate practical prank, or as the most funny ""injureless"" crime anyway!
What you need:
A toilet.
Hydrogen Peroxide.
Sodium Iodide.
The Job:
Put some sodium iodide in the bowl of the toilet.
Empty some hydrogen peroxide in the toilet refill tank.
The Effect:
As someone comes along to flush the toilet it will start bubbling foam then fill the whole bathroom with it's foaminess of Doom.
It's a prank and a half!

Well i dont know any shops that sells chemicals open to the public, plus i do aquire my stuff from kevin's dad(He's a science teacher/professer).
But the best place to buy them is the internet.
Preferrably http://www.kno3.com/ , it's the best place to get your hands on some mischief in a bottle, try it!
It's not that hard to get!
And about the amount, for the Sodium Iodine, squirt it round the bowl like you would with Bleach, and the Hydrogen Peroxide, about 2 or 3 caps full(depending on the size of your cap).
Just experiment with it, until you can adjust it to the amount you think it suits, but it's good stuff when you set the trap at the beginning of lunchtime, and return just before next lesson finding the whole cubicle full of your foamy doom! lol! Good stuff! Good stuff![:)][:)]

Two words: nitrogen triiodide.
Mix ammonia with pure iodine crystals. You want the gel that forms. Paint it on doorhandles, or, even better, taps, but only use a VERY SMALL AMOUNT. Once dry, it is percussion sensetive and highly explosive. Too much will take someone's fingers off.
I can picture in my mind a world without war, a world without hate.
And I can picture us attacking this world, because they'd never expect it.

look up nitrogen triiodide.
if you are a good chemist then the parts will be easy to find. This is the same as flash powder. there are several recipies on line.

Someone correct me if im wrong, but i think..
Hydrogen Peroxide is an oxidising agent which means it has oxygen readily available. On contact with NaI, this oxygen is (somehow?)released and im guessing is cought up in the liquid to form bubbles..
I Think this is the right balanced equation..
2H2O2 + NaI = 2H2O + O2 + Na + I
-
Sorry, dat was to (Steve Vai)
-
Although I have not tried it in a toilet, I think this might be a viable alternative:
(The elements are much easier to obtain…)
Simply use baking soda, (also known as Sodium bicarbonate or Sodium Hydrogen Carbonate (NaHCO3)), and acetic acid (vinegar)
Turn off the valve that feeds water into the tank, and then flush the toilet once to empty the tank.
Pour the vinegar into the tank, and dump a box of baking soda into the bowl.
When the sodium bicarbonate mixes with the acetic acid it should give you a reaction that produces water and carbon dioxide. (Lots of bubbles)…
I haven’t tried it with a NaHCO3 / H2O dilution, but I believe it SHOULD work.

I've done one pretty funny one for a joke.
AMMONIUM TRIIODIDE!!!
it makes a loud bang and makes a brown stain when touched.
It is a contact explosive and is VERY sensitive. a dust sized particle will create an audible pop.
All you need is some iodine crystalls the size of a pencil rubber. and some ammonia hydroxide or any other ammonia solution (the stronger the better) i did my with 0.5mol/dm3
You can also make paint with it and paint key holes and toilet seats...well you get the idea.
Put the small amount of Iodine in a jar and add excess ammonia(12-16 ounces) Swirl the mixture for like 5 minutes and let it settle,make sure its mixed with the ammonia.
filter the mixture and collect the residue.DO NOT DRY IT! it is safe to handle when wet.the solid black stuff is what you want. It becomes pretty useless after a few days.
Put a little into a paper ball and let it dry. you can put it onlop of doors when it is dry (do this very carefully) It exploded in a friend of mine's hand and it hurt a bit.
IT IS VERY LOUD.
My high school teacher threw the filter paper away in her dustbin and it went off! making a big bang.
DO NOT USE LARGE AMOUNTS! CAN CAUSE PERMANENT EAR DAMAGE.

Something me and a couple of friends did when we finished our GCSEs was to put food colouring in the cisterns of all the toilets around school - people flush them, and all this coloured water comes down (but some of the food colouring stained the loos for weeks!).
Also, Branston pickle, on the loo seat and dripping down in the toilet. The teachers put a 'closed for health and safety' notice on that entire toilet block!
Cling film is a good one too.
They are all cheap, easy, and harmless.
And so funny.

About the NaI equation. Does the NaI act as a catalyt in the decay of H2O2? i know MnO2 does that.
The equation goes as follows
H202 + NaI --> H2 + O2 + NaI

table salt is 70% sodium iodide, the glass tube inside a glowstick (that you break to start it) containes hydogen peroxide in a concentration of 35%, so drain the fluid outside the glowstick out (or else it will react and reduce the effectiveness of the foam) and then then break a few and poor the contents into a container, voila, hydogen peroxide

is it ture that eyedrops cause uncontrolable diharea??

I think the reaction for the hydrogen peroxide and sodium iodide thing is as follows:
2NaI + 3H2O2 --> 2NaOH + H2 + 2HI + 2O2
That would make sense becuase the bubbles look like soap bubbles and NaOH is lye (used in making soap) and the oxygen and hydrogen gases would help make the bubbles. The HI is a weak acid and would react a little with the NaOH to make water and NaI again (not that much though). I could be wrong but it makes sense so...I'll stick by it!

As earlier spoken of in this thread every one was wondering how to get sodium. one way that i have heard of but have never attempted is the electralisis of a sodium chloride solution. just take a salution of sodium chloride and run a DC current through two electrodes with large surface areas. On one of the electrodes sodium ions will gather in the form of negative sodium. this is not explosive but if you reverse the electrodes the sodium becomes possitive. Make sure that you do the reversing polarity step in oil or have the hospital on speed dial!
Oh and also the the iron ferrous sulfide bomb is deadly! if you smell the gas (which is the same thing that comes off of rotten eggs) it has already reached the cronicaly toxic point.
please excuse my spelling... i specialize in chemistry not english.

-
Sorry, it is a catalized reaction. I talked to my chemistry teacher and he gave me the reaction:
NaI + 2H2O2 --> NaI + 2H2O + O2
Not sure how much NaI you would use because it is a catalyst. Probably the more is better because there would be more molecules to react with the peroxide and it would run faster.

You guys want a good toilet prank? there isnt much to this one but what you do is take those firework poppers... those little sacks of rocks that you give to kids at halloween and they pop when thrown on the ground??? or you could use that nitrogen triiodide stuff. but anyway place it under the toilet seats (the ones you change for wizzes and dumps) and when the target sits down!?!?!?

I remember at school the teacher did an experiment with caesium behind protective glass. She placed the ceasium in a glass container about 30 cm wide and half full with water. The caesium was only about 2 cm squared and it exploded and shattered the container. It was awesome lol. Back then I always imagined getting a huge chunk and tossing it in a lake to see what would happen. Probably get done for polluting the lake or something.

A joke: mix very well equal amounts of aluminium fine powder and iodine powder (no more than a few grams); put a little piece of very cold ice on it (so that it doesn't melt immediately). When the ice starts melting, the water reacts with the mix, producing a little flame and violet fumes of iodine and aluminium triiodide. Be careful not to breath those fumes!
Al + 3I = AlI3
By the way: those equations with H2O2 and NaI are wrong. This is what happens:
(1) H2O2 + 2NaI = 2Na+ + I2 + 2OH-
(2) H2O2 = H2O + 1/2 O2
Probably, (if pH is >7) there is also the formation of some IO3-:
3I2 + 6OH- = IO3- + 5I- + 3H2O
You can easily see the iodine (I2) produced from the reaction, because the solution becomes brown.

-
another little joke with things quite easy to find: Zinc powder and sulfur powder.
Mix well ~ equal parts in volume of the two, then ignite the mix with a hot flame, like the one of a pen flame. It burns with a yellow-green flame, producing a lot of white fumes.
To ignite the mixture you could also use KNO3/Sugar about 50/50 in weight, very well mixed (the sugar must be ground to fine powder; all powders must be dry).

i know this isnt really a chemically related prank but nevertheless i have always found it funny to wait until a christmas that snows properly (we dont have many in the UK) and get a friend to build u inside a snowman on someones porch. not only does it scare the **** out of them that a snowmans on their porch but when u jump out yellin something it usually sets of the chemical reaction in their panties. oh yeah make sure u get ur friend to knock. hypothermias a bitch.

Another little joke with (quite) simple substances:
Put some copper nitrate (Cu(NO3)2) in a piece of aluminum foil (better if more layers), with some table salt (NaCl) and a bit of water.
Wrap the foil immediately and go away of it.
It will produce reddish-brown fumes (NO2) and hot-liquid squirts.
Be careful!
Don't breath those fumes!
-
this is super funny...well so Ive heard
what you need is
a bathroom with a metal doorhandle
some uninsulated wire
a car battery
and some electric tape
OK open the door so you so u don't have 2 touch the handle
on the inside of the bathroom take out your car battery
and tape a length of wire to the negate and positive poles on the battery
take the positive wire and the negative wire and tape them to the door knob one wire at each end
close the door
and in THEORY it will shock the living daylights out of someone. depending on the battery... a car battery will be the best...Ive never done this so i don't know if it will work
whats its supposed to do is complete the circut charging the door knob. and turning it into the joybuzzer on steroids. either it will shock you or the battery will blow up and may blow off the door. either way it should be a blast
-
That won't work. You just short circuit the battery through the door handle. The most likely outcome is that you will burn out the wires.
-
darn....well then is there any way i can make a door handle shock someone without shorting the battery and frying the wires
-
darn....well then is there any way i can make a door handle shock someone without shorting the battery and frying the wires
Surely it's your father and NOT your wonderful, loving mother you want to shock!
-
neither of you
-
oh, gawd.
the reason you would short the car battery is because you're trying to pass too powerful of a current through too weak of a wire.
also, it would be dangerous to try, you could possibly hurt the person terribly and as they said earlier, practical jokes are meant to be . . . anything but mean. if the victim isn't laughing after the prank, it wasn't a good idea . . .
just use a smaller battery, that would be easier to conceal.
-
like what. a AAA could be too small to really notice and AA would more than likely have the same effect as static electricity I'm assuming the largest i can go without frying the wires is a D size. plus it would be kinda suspicious if you walk into a school bathroom with a backpack... and i can carry a D size battery, around 3 feet of wire and a roll of electric tape on my person and nobody not even know its there

[:(!]BEHAVE!
-
i can't do it in the new school....they will have cameras in every corner of the halls, they will know if i pulled off something like this.
-
well, I don't want to give you any bad ideas ;b but if you want it to succeed, get a lithium AA. More energy, same size. It's worth the money.
-
sounds good
-
If you really want to do this then the first thing you need to do is learn some of the basic science of electric circuits.
-
ok....and im assuming if i can do this with an doorknob i can also do it to an ....locker door....or a metal rod...kinda like a cattle prod
-
well, to complete your objective, yes, you would need knowledge of electrical science. however, if you just want to see something happen, watching a wire short could be just as surprising to the victim.
-
just make sure it's external, you don't want their stuff catching fire if it does short.
-
in that case i will just thick to the doorknob and the cattle prod....i may be a bit of a pyro but i dont want to have to pay for burnt books and what not
-
Do you all understand that,as soon as you connect it up, the wires willoverheat and fail? If the "victim" is there at the time he will see you setting it up; if he's not then he may notice the smell of smoke but there won't be any other effect on him.
Since it won't work with a doorknob it shouldn't suprise you to learn that it also won't work with a locker door or a bit of wire.
Really, learn something about electricity.
-
yeah. you'd have to have some sort of touch-sensitive activator to release energy from the battery into the wire. and that would just get expensive.
If you want to do this so much, just get a real joy buzzer and tape it to the bottom of the doorknob.
-
"yeah. you'd have to have some sort of touch-sensitive activator to release energy from the battery into the wire. and that would just get expensive."
Even then you wouldn't get any current through the victim.
-
very true.
once again, just use a real joy buzzer so you don't burn their fingerprints off.
-
but I suppose it's better than taking a friends orange at lunch and sticking the zinc and copper diodes in it like that "Charging an iPod with an orange" NakedScientists experiment.

Nitrogen Triiodide jst lay it when its wet
-
what does that do????????
-
oh oh
DON'T TELL HIM!!!!!!!!!!!!!!!!!!!!!!!!
-
If he's too dumb to find this
http://en.wikipedia.org/wiki/Nitrogen_triiodide
then I don't see him making use of the information.
If he is bright enough to look on wiki then I hope he has the brains to realise that this is a foolish game to play. If not then I don't see it as my problem that his education has missed out "Don't play with explosives- they might kill you".
-
Keep in mind that wikipedia is not always accurate ...... anyone can go in there and change infomation, why do you think I'm asking these questions on a SCIENCE FORUM! and I know not to play around with explosives from experience, I may be young but I'm not as dumb as I look. I'm a guy, I'm 14 and curious.....that's why I ask questions! I didn't expect to be called dumb for asking them!
-
Asking the questions is not important...trying to find an answer is. Asking other people for the answer is actually less useful than doing some research on your own and figuring it out for yourself. You learn something that way, as opposed to have the answer simply given to you. It's harder that way but if you're really after learning something new and not just spouting "I'm a kid and I ask why" because you've been told that's what kids do then doing research yourself is the way to go. If you have to ask anyone anything it should be to explain some of your research to you because you can't quite understand it...not to tell you the answer.
-
not just spouting "I'm a kid and I ask why" because you've been told that's what kids do
You're so right. Asking and inquiring need to be followed up by thinking and reasoning.
-
BUT even if he did try to find the answer himself, wouldn't it be wise to check the information that he found with, say, a group of people who have studied science? or at least enjoy it? i think that's pretty smart. and it's a little harsh to call someone dumb for asking a question. so act like a grown up and be nice!

When I was in grade school, probably about age 10 and 45 years ago, water fountains were designed such that there was a spoon-like metal hood protecting the spigot from someone getting their lips directly on the plumbing where the water came out. Futhermore there was a bent piece of metal with a hole in it just above the pipe where the water came out. Once in a while someone would take a penny (U.S.) and place it between the water spigot and the bent piece of metal with the hole in it through which the water would otherwise shoot in an arc to land on or near the drain. This only took a second or less to accomplish, so that even if the next person in line (sorry, queue for you in the UK), were standing quite close behind the one fitting the penny in place, they would harldy notice it. The result was that, on turning the lever to get the cold refreshment, the water hit the penny from beneath and slam it against the hole in the piece of metal, forcing it flow, quite forcefully, in a radial pattern along the bottom of the penny, spraying everything for at least a foot around. Many shirts were made this way. It was a lot of fun to watch because most people would stare in disbelief for a split second before reacting. Totally harmless...unless of course, you are the perpetrator and get caught by the
victim.
Another gag I like is to Super-glue a quarter to the middle of the floor in a busy hallway and watch the victim bend over to retrieve it. Sometimes they are so confident of picking it up that they lose balance and make a most amusing recovery. You can take bets on how many times they will try before giving up, or how many other pedestrians they will bowl over or cause to fall in the act. Usually harmless, though the same caveat as above applies.
Let me know if want more!

I always liked the stapler in the jelly gag. Very simple certainly easier than the jelly in the stapler. Theres a guide to doing it here. http://101things4.blogspot.com/2009/04/practical-joke-stapler-in-jelly.html (http://101things4.blogspot.com/2009/04/practical-joke-stapler-in-jelly.html)

Sorry, but I have some difficulty with the language, can you explain me better what is a jelly bowl and what the joke is about?
Thanks.

It's not even funnny, it's a prank that doesn't work. It's been done too many times. It's just like putting cling film over the seat of the toilet, or someones car! After you do this you ask, where is the stapler? [::)]
-
I think it can work, that's why its been done so many times. Whats the cling film in someones car gag?
P.S. LightArrow. A Jelly Bowl is a glass mixing bowl.

As a matter of fact, yes I do want to kill people, but if I gave you a list the police would get suspicious.

A friend of mine was nearly expelled from technical college for leaving silver mirror test bombs in all the litter bins on the science floor. The cleaner left the college and refused to return. Getting expelled from technical college is as easy as climbing Everest in the nude!

That can pall after a bit (I'm told) - pissing them off is more fun.

Getting chucked out of a Tech' is a bit like being bounced out of a leper colony.

Hmmm...
I can think of a better idea that involves 'on' instead off 'off'

In most cases pissing on them would piss them off.
