hello... i just got a open ended investigation and we have to make a kids toy.... on the topic motors and generators i have to make it form scratch, like i need to make the motor as well.....
please any ideas would be great

Motorized catapult would be an idea. This makes it easier too, as you do not need to make a commutator as the motor does not need to constantly spin, if you were to make, say, an aeroplane with a spinning propellor.
