I know this will involve a lot of work, but would it be possible to have a section dedicated to the kitchen science experiments?

I have an 8 year old daughter who is very keen on science experiments and running out of things for her to do, and most stuff on the web revolves around volcanoes......

Dave (daveshorts) is working on a major revamp of the website. As part of that there will be a kitchen science section.. so yes, every chance I think.

Hi Paul

Rosy is spot on. There will be a dedicated section of the new site (due out next month), containing all the kitchen sciences we ever done.

All the ones we have ever done will probably take longer than the rest of the site, but there will certainly be lots there when the new site goes live.

It should be really cool.. Maybe some things geared toward my preschoolers too. YAYYYYYYYY! They love science.... and doing things that they can visually see helps them learn and remember how things work... I love it too, as I am the least scientific minded person around, so I will greatly benifit from this myself!

Well, you must be a good teacher Karen. I went to a good school and science was presented in such a boring way, experiments without much emphasis on the explinations for the result. Science and Mathermatics should be the most enjoyable of all lessons.

KITCHEN SCIENCE - Why sodium street lights make things look orange
on the 18th of february 2007.

For those of you who did this kitchen science experiment; Try repeating the experiment with a cd or dvd, try it under all colours of street lights and even neon sign displays. oh, go on...

Thanks, Dave.

I should have mentioned that it should be a blank disc, and not one that has data on it.

I have only tried it with a blank disc, and my thinking is that the blank CD or DVD is smooth as opposed to the one that has data written on it which has all of those peeks and troths.

Then again you could use a blank and a non-blank disc and compare the two results

I just nooked a unwritten music cd and set timer for 5 seconds and watched a brillant teal blue green sparkle show which was quite lovely. It would have been nice if the sparks were higher then 1 inch up off the CD, but they were lovely anyway. It left a circular pattern on me CD that resembled a brick wall on both sides. almost reminds me of old antique paint that is crackled ! What causes this to spark like that is there some small amount of metal on a CD or what?

Something else I noticed, It smelled slightly not during but when I opened the door for about 15 minutes or so. Just a slight smell, not strong! Is that odor safe or can that be something you shouldn't breath?

Karen, was in an regular cd or a re-writable one? you could try doing it again with another disc of the same type and see if the pattern burned into the disc is the same.

as for the smell when you opened the door. best not to breath too much of it in, just leave the microwave to vent for 15 minutes afterward.

Either type of disk has a thin layer of aluminium in the middle of it. In a conventional CD the data is stored by making pits in this which alter how the light reflects, and in a rewritable one it is done with a layer of a dye above this.

When you put a CD in the microwave, the microwaves induce very large currents to flow in this aluminium layer, the currents are so high that it starts to heat up and change shape. This tends to make it crack up, when a crack forms suddenly the currents often will jump the gap through the insulator/air as a spark. Once a crack forms the currents will tend to go in different routes heating up different bits of aluminium and causing them to crack. This goes on until the pieces of aluminium are too small to build up large currents so it stops cracking, and just gets hot.

Paul it was a regular Staples brand CD-R recordable. 80 minutes 700 MB, 52X, 1x - 52x compatable! I did two of them to see if the pattern was the same. Yes indeed it was ! Same pattern both cds, back and front, They will make charming coasters for a wedding...centerpeice LOL maybe a small Goldyfish bowl on top!! LOL!

Yes, the smell was mild but stunk and I opened my kitchen window and let it air out! wasn't too bad!

nice, i asked the question purely so you could repeat the experiment and see what you got the second time. You would have got a similar pattern. i find it good to do things twice and compare the results, plus you now have two coasters and not one all alone and sad.

We will see - although if it made enough money for Rosy to buy all the shoes she wants to buy, it would only have to sell about 2 copies - all the shoes she needs would probably need a couple of hundred.

We-ell, whilst one of the pairs of shoes I threw away at the weekend were only 6 months old, I wore them for work every day for 4 months... and the others were almost 10 years old, were my school shoes for two years and were the old-but-tough shoes I wore when I didn't want to damage my other shoes ever since. Tho' the latter were infact probably officially boys shoes.
