This set contains the essential materials used in construction of a simple electric circuit with a small electric motor, a switch and a battery. This kit is also used to make an air propelled motor boat known as Car-Boat or Carboat.

This kit includes one electric motor, battery holder for 2 AA batteries, one simple switch, 2 propellers, 4 wheels, 2 axle dowels, 4 small screws, 2 plastic straws and 2 connection wires. It does not include styrofoam, paint and white glue.

If you add some wheels to your boat, then you will have a hybrid vehicle that may be called a car-boat or CarBoat because it can drive both on land and on water.
