About Radiometer Solar Spinning Tin-man Heart - Powered
"...a heart is not judged by how much you love, but by how much you are loved by others" - Wizard of Oz Physics meets romance in this unique reimagination of the tin man's heart. Try it out yourself and watch thermodynamics in action. The radiometer's four vane rotor spins continuously up to 3,000 RPM. Inside the hand-blown glass sphere are four heart shaped vanes, each with a black and silvered side. The heart vanes rotate when exposed to light, spinning faster with more intense light. The motion depends on having just the right degree of vacuum in the sphere, and is caused by the transfer of heat to the hearts.
