Thermite!~

[Mark C]

I made that once back in high school. I was in charge of taking inventory of the chemistry supply closet... a few things may not have made the final list.

It's a bit tricky to light, we used a strip of magnesium. Once lit, the small pile of dust turned into a 6 ft flame. We lit it in a sand bath, the fire was hot enough to melt the sand, and there were little balls of iron mixed in from the reaction byproducts. Definitely a fun experiment!
