Fun With Chemistry

Recently all kinds of interesting things have been delivered to our door for Dave, resulting in all kinds of fun chemistry experiments. Mostly these involve fire. In this matter I feel that Dave has an excellent understanding of our children’s interests, but let’s be honest, here — this also reflects his interests.

The pictures below are from lighting off some experimental bits of rocket candy. This is a simple concoction, made with sugar, that burns with impressive heat and very little ash. If packed into a PVC pipe, it can also burn for quite a while.

There have also been experiments with thermite, made of two not-very-flammable components that, when combined, produce something that burns hot enough to melt metal. Dave did a couple of experiments with some tinfoil and springs from our (sadly defunct) trampoline. He wasn’t able to weld the springs together (or at least, they broke apart again easily), but he really toasted that tinfoil.
