Product Details

Dramatic demonstration with only the heat from your hand. Two glass bulbs are connected with a glass tube and contain a colored, volatile liquid. Holding one of the bulbs in your hand causes the liquid to boil causing vapor to move into the other bulb where it bubbles rapidly. Caution: Never use with any heat source warmer than body temperature.
