Description

Charles' Law, also known as the law of volumes, states that a volume of gas, at a constant pressure, expands as the temperature increases. Heat is the transfer of energy from one part of a substance to another. Air pressure is the force exerted by air, whether compressed or unconfined, on any surface in contact with it. Energy can transfer by radiation, heat conduction, convection, electrical power transmission and mechanical work. How can you demonstrate all of this to your students? With a hand boiler! It is made of two delicate glass bulbs connected by twisted-glass tubing. When holding the base in your hand, colored water moves up through the tube to the top bulb and appears to boil. It's mesmerizing: so pretty and fascinating! Recommended for use with students age 14+, but you could carefully supervise younger children to demonstrate the scientific principles. All you need is a warm hand! The glass bulbs are very thin so heat is easily transferred. These are to be handled with care! There are 4 colors of water with 4 tube designs: green swirl, blue figure-8, red heart and purple spiral. Our choice unless you specify at time of order. About 7 tall and 1.5 across the bottom bulb. ~ Sara

This is another unique desk toy for those little moments when you need a break to sit and stare at something. Simply hold the larger glass bulb in your hand, and the liquid will swirl through the glass to the top, also giving the appearance of boiling water!
