Forget lava lamps or firepits; these fire tornadoes will definitely impress your friends and family. The best part of the whole project is its simplicity. If you can cut glass without hurting yourself in the process, you can make a fire tornado.
As the air comes through the uneven glass, the currents spin the fire (or smoke) upward in the glass. You can use lithium for a red color, or even mix your colors if you feel so inclined! The Backyard Scientist gives you instructions for everything.
