Description
 
Gently cup the lower bulb of the handboiler in your hand and watch the liquid 'Boil' to the top! The heat from your hand is actually forcing the liquid up the tube and then causes it to bubble through the liquid. A great and mesmerizing desktop toy. Four different designs with different color liquid. Caution: Made of fragile glass. Handle with care as the liquid is harmless but will stain!
