At home, I performed a science experiment which contained static electricity. It worked and worked really well. This is how it happens:
When you put the comb on your hair or a balloon, tiny bits of atoms from your hair, called electrons are collected on the comb.
It is like when a magnet is attracted to certain metals.
When you bring the negatively charged comb or balloon near the water, it is attracted to the positive force of the water. This is what causes it to push the water. Then the water bends so it is not straight.
How to do it:
Turn on the water so it has a thin stream.
Take your comb or balloon and brush it through your hair ten times.
Now slowly bring your comb or balloon close to the water (without making contact) and you will see that the water bends, this is because it is attracted to the static electricity off the comb.
What do you think?
Why don’t you have a go?
