Does anyone know a good chemical reaction experiment?

Question

I'd like to do a good one for school, preferably an explosive one!

Answer 1

mentos and diet coke

stick a couple of mentos in a diet coke bottle and run away! EXPLOSION!

hydrogen and fire

(fill hydrogen in a balloon and light a match near it) Then light a match near helium filled balloons...observe the difference. Not too dangerous. My gen chem teacher did this experiment in the classroom.

EXPLOSION

Answer 2

Shave off a match head, roll the powder in a thin aluminum foil, place on a flat stone and hit with another stone.

You will get a sharp bang as the aluminum combines with the oxidants in the match head initiated by the temperature rise on impact.

Answer 3

natrium + water --> simply explosive...

hehe...

be careful not to use too much natrium though...

Answer 4

Gerard Way+Frank Iero+Chemical Romcance=EXPLOSIVE HOTTNESS!

Answer 5

vinegar and baking soda
