We're Sold On Solar Cells

Solar kits like this one are great for learning about the sun remotely because learning about it in-person is such a hassle. It’s so far away, and so hot. Better to just learn down here with this Solar Cell kit from Tedco® Toys. Includes a 2-1/8" x 1-1/8" 1/2-volt solar cell, a small DC motor and a 4" dia diffraction grating disc that can mount to the motor shaft. Also comes with an excellent instruction sheet. Made in Hong Kong, assembled in the USA. Ages 9+.
