 2.Tie up the weighted object with the cord.
 
 3.Fix the assembled items 1m or higher above the ground.
 
 4.Lift the weighted object to the top using the cord.
 
 5.Release the object towards the ground.

We can also conduct the experiment by using a microwave tray motor instead of the toy car's motor.

It requires no operating cost, no electricity and no batteries.
 
 Gravity light works by lifting a weight - in this case a simple weighted object.
 As it descends slowly, it actuates a pulley system connected to the motor that
 converts the mechanical energy (Kinetic Energy) produced by the movement
 into electricity, thus powering the LED Light.
