Mini Hand Boiler

*Assorted Colors - Shipped at Random.

Hand boilers are sometimes known as love meters. You hold the lower bulb to prove how passionate you are - the more love you express, the faster the meter fills to the top! An easy way to prove how hot you really are. The slightly less romantic, more scientific explanation for the phenomenon is that the heat from your body causes temperature and pressure to rise inside the lower bulb. The liquid travels from high to low pressure (going up!), and expanding gas bubbles through the liquid, making it look like it's boiling. This is a handy little science experiment that fits right into the palm of your hand (but if you prefer to believe it's the heat from your passion making the liquid rise, we don't blame you). Popular as a collector's item or as a souvenir, hand boilers demonstrate the science of temperature and gas pressure change. But, really, they are just plain fun! This small version packs a ton of fun into a mini science toy. For ages 10+
