PIRA Classification: 5K40.40
Description: The motor seen in the previous demos is
connected to a small light and a battery. The rotating arm of the motor
has string wrapped around it, which is connected to a mass over a pulley.
When the battery is connected to the motor, the mass will rise. The
switch is then placed in its neutral position to allow the mass to fall,
thus gain speed. When the mass is halfway down, the switch is thrown to
light the bulb.
Special Instructions: If the mass doesn't build up enough speed on
its way down, the bulb may not light.
