hand-blown glass radiometers illustrate a simple principle of
physics - that light can be transformed into kinetic energy which
results in movement. The carefully balanced vanes inside the glass
are black on one side and silver on the other. The black side
absorbs light faster than the silver, causing the vane to spin.
Even if you're not interested in the science aspect of radiometers,
they are beautiful hanging in a window. Sold individually, they
can be hung together to form a chain. Select from clear or blue.
Measures 2 1/4" in diameter.
experienced this – coming back to your car after being parked
in the blistering sun where the steering wheel is so hot, you
can’t even touch it. The solar-powered AutoVent Turbo is the ideal
way to securely ventilate a parked car. It exchanges the air in
your vehicle approximately every 20 minutes to help keep temperatures
at a more manageable level. Simply place it on top of the car
window and roll it closed. Three interlocking security strips
are designed to fit any car window.
