Q
How os a car spray painted?
A
By charging the car with positive electricity, then charging the paint with negative electricity, the opposite charges attract. Anywhere the paint is sprayed in the room (provided it isn’t REALLY far away, it is going to be attracted to the car. The droplets won’t go near each other, as the same charges repel more. This means that the car will be evenly painted
