Radiometer

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. ...Read more

Red Light-Up Led Gyroscope with Stunt Stand.

The 2-3/4" tall x 2" dia gyro is metal and plastic, with a small plastic stunt stand, and will continue to balance intriguingly, even If you somehow manage to wear out the LED's non-replaceable batteries.

The Famous Drinking Bird

Drinking Bird. A rather dumb looking 6" bird with a felt covered head and has plastic feet. Worse, he cannot get his fill of water. You buy the drinks. Fluid inside condenses from the evaporative cooling of the water off the bird's beak, making it top heavy and dunking it back into the water. The condensate rejoins the liquid pool in the bird's bulb, and he tips up again. Process continues indefinitely. It works, but it's not any more than moderately well made, and not any more than moderately priced. WARNING! The fluid and dye inside the bird can permanently stain, and the bird's glass body can easily be broken. Children are fascinated by the bobbing bird, and the educational possibilities are great. But they should watch it, not fondle it!! ...Read more
