Robentino Car N

My Thing is a propeller-powered Pinewood Derby-style car that is designed to run smoothly along a track in as little time as thought possible. A PASCO™ fan cart accessory is able to clip onto the sides of the vehicle (fan facing backwards, obviously!), and two (2) pairs of low-friction wheels can be attached to the underside, fitting in the slots which can be found there. Note that the fan requires four (4) AA batteries as well.
