Last week i was bored so i decided to make a toothbrush robot. It cost me less than 5 dollars and it was a fun project.
Materials:
1. head of a toothbrush
2. small vibrating motor
3. button cell battery
4. tape
Procedure:
1. Take the head of the toothbrush and put tape on the non-bristled side.
2. Attach the battery to one end and the motor to the other end.
3. Make sure one of the wires is touching the positive side of the battery and the other wire should touch the negative side of the battery.
Now watch your toothbrush robot roam the space.
