Hand Boilers

• Dazzle your friends and family with science! A hand boiler is made of hand-blown glass and filled with a special liquid called ethyl alcohol. The boiler consists of a larger lower bulb and smaller upper bulb, connected together by a twisting glass tube. When you hold the lower half the liquid shoots up and seems to boil, hold the top section and the liquid returns to the bottom, ready to start again!
