Description
Demonstrate differential thermal expansion and how thermostats work with this fun demo.
When heated in a Bunsen burner flame, this bi-metallic strip bends. The strip is steel on one side and brass on the other side. Since brass expands more than steel, the strip becomes longer on the brass side. As it cools, it becomes straight again.
