Hand Made Glass Radiometers
 (Select Quantity Below)
|
See the science and beauty of the power of the sun come together in this exquisite hand-blown, hand-crafted glass radiometer.
The highly sensitive vanes carefully balanced inside the radiometers take on energy when struck by the molecules heated by sunlight.
The vanes' shiny sides reflect the heat, which is absorbed by the dark sides. Energy is released as the heated molecules kick away at great speeds, causing the vanes to revolve within the vacuum.
