The existence and flow of these electric charges from one matter to another result in a phenomenon known as electricity. Current electricity is the electricity produced by electric charges across the electric field with a conductor. Static electricity is the electricity produced by friction caused when two or more objects are rubbed.
In this experiment, we are generating static electricity by rubbing plastic objects against human hair. The flow of static electricity happens only when there is an equal amount of protons and electrons on the surface or within the two solid materials. When the two solid objects rubbed against each other, free electrons, i. However, the amount of electricity produced depends on the number of electric charges accumulated and free flow from one object to another.
In our experiment, dry hair is the best electric charge acquiring object when rubbed against other objects. Let us apply the same science to the television in our home. What do you think the reason could be behind TV cabin receives less dust than TV screen? When the TV is switched on, the electrons flow from the back end to the main screen—these electrons on the screen cause it to charge. Any charged object attracts tiny particles such as dust. So, the charged screen attracts dust in a higher amount compared to the non-charged television cabinet.
Similarly, the object comb or inflated balloon or any plastic material like PVC pipe rubbed against human hair collects the free electrons or tiny charged particles. And as these electrons are negatively charged, the comb or any other plastic material becomes negatively charged. Hence, they attract positively charged objects. Water shows neutral electric charges as it encompasses an equal number of protons and electrons. But when the negatively charged object comes in close contact, the matching ions repel each other and move away from the object, pushing the positively charged ions in front.
Hence, water emits positive force when a negatively charged object comes in close contact. We can represent this as magnetism because even the magnets attract each other when there are two opposite poles meet. Since there is enough force to drag the thin water flow, the water stream shows little movement when a negatively charged object comes in close contact. Now, bring it near the thin flow of water faucet. Observe how amazingly the water stream moves and reveals the presence of static electricity.
Then, take a comb or balloon and rub it against your dry hair. Then, see the magical movement of tiny tissue papers towards the comb or balloon. The answer is static electricity. Static electricity often happens when you rub things together. Combing your hair creates static electricity. Negatively charged particles electrons move from your hair onto the comb.
This makes the comb negatively charged. When the negatively charged comb comes near the water, it repels the electrons in the water, so that the side of the water nearest the comb then has a positive charge.
The attraction between this positive charge and the negatively charged comb results in a net force on the water, bending the stream.

Rub the inflated balloon on your hair several times until some of your hair starts sticking to the balloon when you lift the balloon.
Place the balloon near, but not touching, the stream of water.
