Here's another great vapor pressure demonstration! When the handboiler is held in your warm hand, liquid quickly travels from the bottom bulb to the top along with numerous bubbles, giving the appearance of boiling. What's really happening? The air around the liquid is warmed and expands. The pressure from the air pushes on the liquid, forcing it to the top bulb. We also include instructions for a great distillation activity you can conduct with the handboiler. Available at teachersource.com/product/hand-boiler/energy-conversion
