6 in 1 Educational Solar Kit

$25.95

No batteries or screws needed just snap the pieces together and wire in the solar panel and gear box to see just how much power the sun can supply! Models that can be built are: windmill, tethered revolving plane, airboat, plane, car, and puppy. Simple but very effective. The only tool needed in the diagonal cutter for removing the plastic components from the mold tree.
