Water Bottle Experiment Pressure

If we asked you to blow up a balloon inside of a bottle or better yet fill that balloon with water you d probably think that it s no problem.

Water bottle experiment pressure. The highest hole should show the least pressure. When you release the bottle. The water balloon in a bottle experiment will show you just how powerful air pressure actually is and you ll get to play some fun tricks on your friends. When the cap goes off the temperature inside the bottle cools causing the water molecules to condense into vapor.

Follow up discussion questions. Now uncap the lid and let the water begin to flow. This causes the temperature inside the bottle to rise. A simple and fun and easy pressure experiment is awesome.

Every 10m you go under water the pressure increases by one atmosphere. You ll need to get a big powerful flashlight to shine through the bottle of water. At cooler temperatures the water vapor forms around dust particles to condense. As a result the outside air pressure which is greater pushes down on the surface of the liquid forcing it to move up the straw.

Today we are making and demonstrating air pressure with water and balloon. As the water level in the bottle decreases so should the flow rate from each of the holes but the proportions should remain the same. Explore pressure and force with a plastic bottle and water. Turn on the flashlight and turn off the lights in the room.

Water is quite heavy so the water at the top of your bottle will compress the water below so the deeper you go the higher the pressure. Air pressure experiment is a cool experiment that can be great science fair ideas. The pressure did not exert itself on the water so the water did not rise up your straw. This is also how clouds form in the sky.

The water flowing from the lowest hole should spurt the furthest as it is under the most pressure. This means that if you make holes in the side the water next to the deeper holes will be pushed out much harder so it comes out quicker and travels further. When some of you sipped on the straw with the holes however the air pressure was pulled directly inside via the holes. Place the bottle on the counter close to the sink so the streams of water flow into the sink.

We can make a lot of experiment related to air pressure. Cool science experiments using pretty much nothing but water. This awesome physics project can be easily made at your house or at classroom. This is why submarines and deep sea diving suits have to be so strong to avoid being crushed.

When you squeeze the bottle the pressure increases.
