xkcd Describes What Would Happen If Someone Made a Lava Lamp Using Real Lava

In the latest edition of “What If?” by xkcd, Randall Munroe answers a sixth grade teacher who asks what would happen were someone to make a lava lamp using actual lava. Munroe calls the project “surprisingly reasonable” by his own standards.

At the very least, I’m guessing you would lose your teaching license, and possibly some of the students in the front row. But you could do it.
