Procedure

    1. Take the single hanger and hold it so the hanger hook is down.

    2. Tape the thruster with the propeller facing up inside the hook.

    3. Tape the two film canisters with lids on, to the upper part of the hanger.

    4. Tape enough weights to the hanger, to allow the hanger to float right at the surface of the water.

    5. Strip the insulation off of both of the wire ends about 1”.

    6. Twist one end of a wire to one terminal of the motor and twist the other wire to the other terminal of the motor. You can braid the wires together to make it neater.

    7. Tape the other end of each wire to a stir stick or chopstick. Make sure that the noninsulated part of the wire is hanging over the end of the stir stick.

Place in the water and touch one stir stick end to one battery terminal and the other stir stick end to the other battery terminal to power the motor. If it doesn’t sink you may try switching the polarity, which reverses the motor and prop direction. If it still doesn’t sink then you may need to tape some additional weights to the hanger.
