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.
This liquid inside the boiler is special because it appears to boil at a low temperature.
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!
Note: Glass construction, not intended as a toy.
17.5cm tall.
Recommended for Adults only.
