How to Create a Vacuum with Running Water

Create a vacuum with running water and a garden hose.

This type of vacuuming relies on gravity to start and maintain the vacuum's suction. The body of water being vacuumed must be higher than the draining point for water to flow and create the vacuum effect.

1. Attach one end of a garden hose to a water faucet. Plug the other end of the garden hose.

2. Turn on the water faucet to begin filling the garden hose with water. This process primes the hose, readying it for suction. Turn the faucet off once the hose is full of water.

3. Unscrew the hose from the faucet and insert a plug into the hose end to prevent water loss. Set one end of the hose down into the body of water you want to vacuum. Place the other end of the hose onto an open area lower than the body of water being vacuumed.

4. Unplug the garden hose end down in the body of water. Unplug the other hose end. Due to gravity, water begins flowing through the hose, creating a vacuum. Maneuver the hose end in the body of water to direct the vacuum.
