Why does balloon stick to wall

Key concepts Electricity Electronics Insulators Conductors. Introduction Have you ever wondered why rubbing a balloon or a blanket—or even a winter hat—on your head makes your hair stand up?

The effect is due to static electricity, but how is the static electricity made, and why does it make your hair stand on end? Static electricity is the buildup of electrical charge in an object.

Sometimes static electricity can suddenly discharge, such as when a bolt of lightning flashes through the sky. Other times, static electricity can cause objects to cling to one another. Think of how socks fresh out of the dryer stick together. This happens when objects have opposite charges, positive and negative, which attract. Objects with the same charges repel one another. Could enough static electricity make a balloon stick to a wall?

How much do you think you would have to rub it? Background When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity.

Ben Davis February 1, Why does the balloon stick to the wall after it is rubbed on the wool sweater? What happens to the negative charges in the wall when the balloon is brought near them? It is the attraction between the positively charged area of the wall and the negatively charged balloon that results in the balloon "sticking" to the board. Over time, electrons will transfer from the balloon to the wall, causing the balloon to become uncharged and fall to the floor.

Some materials lose electrons more easily than others. The more easily the material loses electrons, the better it will "charge up" the balloon.

Describe the movement of electrons from one material to another. Per Student: balloon a clean blackboard, whiteboard, or dry wall space. How are the balloons sticking to the board? What did rubbing against a sleeve do to the balloon? Something interesting that I stumbled upon while doing this research was some different materials that cause a lot of static electricity are rabbit fur, human hair, cat fur, glass, and dry human skin!
