Solar Aircraft Balance Toy - Black Propeller Kinetic Art Balancing Decompression Science Physics Plane for Home Office Desk - WJ156

Q: I try to make the solar work, so I put two light on top of the airplane, but motor did not work. Is this only work with sun?

Works best with DIRECT sunlight. Might want to try a lamp with an incandescent bulb (if you can find one). LED light do not work well, if at all. Once exposed to the right kind of light, you might have to give the motor a bit of manual start to get it going.

Q: Does the propeller start automatically? Also description says will not work through glass??

The propeller does start automatically when the plane is in bright sunlight. It will work through a window, but it will have to have very bright, direct sunlight. Mine works about a fourth of the time as my other solar toys because they don’t need as much bright light. When it gets enough light, it will go like crazy, and is fun to watch!
