## How does the air pressure experiment work?

Air presses down equally on the water in the bottle and in the straw when there is no balloon present ( or the balloon is pegged ) but when the peg is removed, air from the balloon increases the air pressure in the bottle which pushes down on the water, forcing it through the straw.

## What are some air pressure experiments?

5 Ways to Demonstrate Air Pressure to Children

• Water Glass Trick. Fill a cup one-third with water.
• Fountain Bottle. Fill a 2-liter soda bottle half full of water.
• Ping-Pong Funnel. Put a ping-pong ball inside the wide part of a funnel and blow hard into the narrow end.
• The Million Dollar Bet.
• Kissing Balloons.

Can you make a cloud in a jar?

Place a 3-5 pieces of ice on top of the lid of the jar. Watch the top of the jar carefully and you will see a cloud begin to form. After observing the cloud in the jar, remove the lid and watch the cloud escape out of the jar.

### How do you do air pressure in water experiment for kids?

How do you demonstrate pressure?

1. Take a plastic water bottle and fill it with water to its half way.
2. Place a straw into its neck part and seal the leaky edges using putty or clay.
3. Blow heavily into the straw which creates increased air pressure inside the bottle.

### Can water pressure experiment?

Water pressure can push water through pipes and hoses. Here is an easy water pressure experiment. Simply poke a few holes at different heights on a bottle and watch water pressure at work. You will find that water pressure changes depending how the height of the holes.

How can we demonstrate air pressure using a straw?

Wrap a lump of clay around the straw to form a seal. Blow hard into the strawâ€”then stand back. Your blowing increases the air pressure inside the sealed bottle. This higher pressure pushes on the water and forces it up and out the straw.

#### How do we use pressure in everyday life?

Applications of Pressure in Daily Life

• The area of the edge of a knife’s blade is extremely small.
• Syringes are used to take blood for blood tests.
• When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.
