Tonight (in the name of science) we conducted Thermite Experiment #2. It was a great success. We got a nice thermite reaction, made some nice pieces of melted iron that the kids got to keep as souvenirs, melted a hole through the frying pan we had under the experiment (even though it was full of sand), and killed a good patch of lawn.
Video available here.

That is the molten iron pouring out the bottom of the cruicible into the frying pan full of sand.

We got some interesting pieces of iron, and even some sand that had fused in the frying pan--little melted balls of sand that weren't magnetic.
We are pondering our next experiment. . .
