Whats A Cool science Experiment to do it must be filmable/interesting?

Question

yeah i got to do 1 so yeah

Answer 1

Don't do these indoors...

Put some HCL into a plastic 2 liter soda bottle (enough to fill like 1/8), add aluminum shavings. Cap the bottle and shake (quickly, quickly). Toss the bottle. Film the explosion.

Grind up powdered magnesium and solid oxygen (magnesium you can get from school, I'll bet, and welding torches use solid oxygen sticks). Grind/mix thoroughly (you want as fine a powder as possible, to maximize surface area). Set camera up on tripod. Light mixture. Run, as it burns with a powerful intensity and will most likely damage whatever surface it is sitting on.

Answer 2

Here are a few good ones:

(Collapsing Can is good and easy to find materials - take an empty soda can (with a small amt of water in it. Bring the water to a boil. Have an ice bath sitting nearby. With a pair of tongs, grab the soda can, turn it upside down into the water bath. Watch what happens.)
