Hi!
I did this demonstration and burned my hand because the gummi bear wouldn¹t
slide down the tube and I foolishly ramroded it in using a combustion spoon
which I should have bent back on itself to be safe but didn¹t... A much
safer demo that unfortunately doesn¹t involve a sacrifice is called the M&M
massacre. I use 2 M&Ms- they slide down the tube easily and don¹t
stick...avoid the temptation to keep putting in more M&M¹s even though there
may be a lot of leftover molten potassium perchlorate.
The kids loved it....I am a teacher who likes to ³fire² students up once in
a while with this sort of thing... I save the videos for things I really
can¹t do myself like thermonuclear explosions....
