Experience this sphere powered by the sun! The vanes in the Radiometer are alternately dark and light in color. When the light strikes these vanes it transfers heat to each one - but not at the same degree. The lighter vane reflects the rays and the darker vane absorbs the rays. The stronger the light, the more energy there is causing the vanes to spin faster.
TEDCO is a manufacturer of Fine Science and Educational Toys.
TEDCO was first established as a research & development company by the late Ralph Teetor. Mr. Teetor was a well-known and highly respected investor who started TEDCO (Teetor Engineering Development Company) as a vehicle to foster his inventions. His most renowned accomplishment is the "cruise control" on your automobile. Mr. Teetor was blinded at an early age, yet he did not allow his lack of sight to hinder his creative genius. He was president of the former Perfect Circle Corporation and was inducted posthumously into the Automotive Hall of Fame. So we are very impressed about Mr. Teetor, and TEDCO. So Set Shop has requested a dealership, and we have become one of TEDCO's dealer.
The Sun Light Print Kit could become your children's best friend on their spcial sick day from school. Tedco has many Fine Science and Educational Toys for their rainy day. |
