Hand Bubbler Science Kits for Kids easy science fair project
This Hand Bubbler STEM Toys for 14+ year olds for girls and boys demonstrates energy transfer in a cool, fun way -- try it yourself! As you hold it at the bottom, your hand warms the liquid and it starts to vaporize, expanding its way and bubbling through the tubes to the upper chamber. When all the liquid has bubbled to the top, let go and as the liquid cools, it moves back down to the lower chamber. The science behind it is based upon Charles' law by Jacques Charles who in 1787 discovered that a gas' volume is proportional to its absolute temperature -- V1/T1 = V2/T2. At a constant pressure (inside the glass), the gas' volume increases as the temperature increases. Now you know! (#9A195) A ComputerGear exclusive.Item in stock unless noted above.

WARNING: Not intended as a toy for children. Contains Ethyl Alcohol. Avoid contact with eyes. In case of eye contact, flush thoroughly with water. If irritation persists, get medical attention. Do not use near heat or flames; only warm using your hand. Liquid will stain if glass is broken. Keep out of reach of children or at least watch 'em if you let them try it.
