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.

hidrogen peroxide is used for bleeching hair, you get it from your local pharmacy/chemist. i am also trying to find sodium iodine, i just saw that toilet thing being done on tv, ill post the video tomorrow.

since ye all seem to love doing stuff to the alkali metals with water has it not occured to anyone what kind of reaction you get with an acid and said metal,sodium and vinegar... never try potassium, that is why the lump of sodium in the swimming pool got such a good bang instead of just fizzing around..

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.

be carefull and safe.

lookin through this post again, havent been on forum for ages, i have a couple of questions

the sodium iodide and hydrogen peroxide reaction, why does it work? can someone please explain the equations or something to me, and also what would substitute the sodium iodide? any iodine based salt or what?

thanks, and sorry if my questions seem stupid, the GCSE course isnt the peak of chemical enlightenment lol

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

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

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.

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.
