Caution: This experiment uses a flame. Flame could burn you so be careful!
Metal Can Opener
1. Place the metal can opener on the stove top.
2. Place the Brazil nut at the end of the can opener.
3. Hold a lighter near on end of the Brazil nut until it lights (it may take a couple of seconds).
The Brazil nut will not only catch on fire but will burn for several minutes! The oil in the nut is quite flammable (and fattening) and so the nut will burn for quite a while. So next time there's a power outage, feel free to say "Hold on! I'll go get the nuts!!!"
