This is because the rubbing creates a negative charge that is carried by electrons . The electrons can build up to produce static electricity. ... Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges
Why does your hair stand up after rubbing it with a balloon?
Remember, objects with the same charge repel each other . Because they have the same charge, your hair will stand on end. ... When you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon.
What happens when you rub your hair against a balloon?
Rubbing the balloon against hair or wool causes electrons to move from the hair or wool to the balloon . Because electrons are negatively charged, the balloon acquires a net negative charge. The balloon’s negative charges are attracted to the positive charges in the can, and so the can rolls toward the balloon.
Why would a balloon attract your hair without touching it?
When a rubber balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge, and leaving the hair with a net positive charge. As the balloon is pulled away, the opposite charge on the hair causes it to be attracted to the balloon.
What charges make your hair stand up?
It’s because of static electricity ! When you rub the balloon on your hair, you’re covering it with little negative charges. Now that each of the hairs has the same charge, they want to repel each other. In other words, the hairs try to get as far away from each other as possible.
What happens to the stream of water when you hold the charged balloon next to it?
When you bring the charged balloon near to the water it pushes electrons away, leaving a positively charged area which is attracted to the balloon . The water coming from the tap is neutral with positive and negative charges. ... This positively charged water is attracted to the balloon so the stream is deflected.
Is rubbing a balloon on your head friction?
Electrostatic charges are not caused by friction, although many assume this to be the case.

Why does rubbing a balloon on your sweater allow the balloon to stick to a wall or the ceiling?
Why does rubbing a balloon on your sweater allow the balloon to stick to a wall or the ceiling? You are adding a surplus of electrons (negative charges) to the surface of the balloon . As the two come in contact, the balloon will stick because of the rule that opposites attract (positive to negative).
What brings two rubbed balloons near each other?
Negative charges attract to positive charges . If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
How does a body becomes positively charged?

What is hair attracted to?
