Do something fun. Find out why Potassium 'splodes in water, then do a demo of it. You may want to talk to your teacher about it first, though.

What would I make the bio domes out of if I chose this one?Superior Mind wrote:
I was thinking a demonstration of greenhouse gasses in a controlled environment. Make 3 small bio domes, each with some small plants inside. Have equally intense lights on each dome. One dome leave as is, water it, etc. Second dome burn a match in it every day. Third dome, burn a match in it every hour. Then record the changes in the plants.
Damn teachers, ruining fun with potassium before it's even thought of._j5689_ wrote:

No, volcanoes in general, someone mentioned it and he said you can't use that one.Noobeater wrote:

You could always show of geothermal power by making a model of ...wait that would require a pump and a flame and piping etc. which would be a bit too much effort imo.
EDIT: Was it just potassium based experiments your teacher forbid? If so then use Caesium with water, fun times.
then just throw a shitload of potassium into water_j5689_ wrote:

Geothermal power is not volcanoes. Geothermal power is using ground source heat pumps to pump water down a hole in the ground (roughly 30-100 metres, depending on location and the amount of heat wanted) which provides warm water which can then be used in radiator systems in buildings. The same works at a greater depth for creating electricity by making a deepeer hole and thus getting hotter water.Hurricane2k9 wrote:

lithium works well too.
you could also investigate why ammonium nitrate is used in explosives, and then do a small demonstration
Would be epic, except that Frankium is so radioactive its decayed away in under 30 seconds. I suggest caesium instead as its the next best thing.Mint Sauce wrote:
Put some Francium in water.
