# Static Electricity Demonstration: Bending Flowing Water

by Ron Kurtus (revised 17 November 2012)

Notice that after charging a comb with static electricity, you can cause a stream of water to bend. This would be a good phenomenon to demonstrate.

Questions you may have include:

• What is the purpose of the experiment?
• What research must be done?
• What is the experiment?

This lesson will answer those questions.

## Initial questions

Initial questions include:

• Why does water bend?
• Can I make it bend more?
• Can I make it bend the other direction?
• What is the best type of comb to use?

## Possible factors

What are possible factors in bending water are:

• Type of comb used
• Times combed through hair
• Pressure of water
• Distance from stream

## Test procedure

You can bend a stream of water with a comb or other items that is charged with static electricity. The procedure to do this is:

1. Turn on the faucet so that the water runs slowly but just runs smoothly without breaking up.
2. Create static electricity on a non-conductor. You can use a plastic comb  to comb your hair, or you can rub a plastic rod with some wool..
3. Place the charged object near the running stream of water.

The stream of water should bend. Can you explain why?

## Other experiments with bending water

• Try bending water with different charged items.
• Try bending other liquids, such as cooking oil
• Try turning the water so slow that it breaks up. What happens? Why?
• Try turning the faucet so the water runs faster. What happens? Why?
• Try two combs in different positions.
• Try different sources of static electricity.
