Crocodile clips are used to create flexible, temporary experimental electrical connection in laboratories.
The device could be between two wires or between an electrical lead and the anode or cathode of a device (i.e. the entrance and exit points of an electrical current).
The cloth rubbing wool is used to perform the static electricity experiment.
A cloth rubbing wool is used for rubbing against different materials, such as glass, plastic, balloon, wax.
Wool cloth is used to demonstrate experiments for balloon and wool cloth.
When rubbing a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge.
If both balloons are rubbed with wool, they will both have same charge (negative) and therefore will repel each other. When you spray water near the balloons.
The water droplets carry the charges away from the balloons, leaving them uncharged. As the balloons become neutral, they will fall back together.
