The hand boiler is a classic science tool that inspires wonder and scientific investigation. It demonstrates Charles's Law and energy transfer. Wrap your hand around the base of the hand boiler and watch as the blue liquid moves up the glass vessel and appears to boil. The hand boiler is approximately 7 inches tall with a 2 inch base. It is great for science lessons and STEM activities, but it is not recommended for younger children because it is made of glass (14+).
CAUTION:The liquid can stain if the sculpture breaks, so please use with caution. The seller is not responsible for damage during or after use.
