Water Bottle Experiment Air Pressure

This experiment will allow you to create a tornado in a bottle.

Water bottle experiment air pressure. The cartesian diver experiment requires a plastic bottle filled with water and some modeling clay. Obtain an empty plastic bottle. This experiment works best with a bottle that has relatively thin plastic. Make an exciting bottle rocket using an empty plastic bottle cardboard a cork and an air pump.

Quickly releasing the bottle lowers the pressure and cools the air. Squeeze the bottle in the middle and. Every 10m you go under water the pressure increases by one atmosphere. Once that happens the pressure outside the bottle is greater and pushes the egg down into the bottle.

In some situations air pressure is stronger than gravity. When some of you sipped on the straw with the holes however the air pressure was pulled directly inside via the holes. Even though you put a hole in the water bottle since the cap is on the air pressure pushing on the outside of the bottle will keep the water inside. That cooling causes some of the water vapor to condense back into liquid water.

The match uses up the air inside the bottle. The pressure did not exert itself on the water so the water did not rise up your straw. 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. Having fun with friends and learning along the way.

Making a bottle rocket. While this step isn t entirely necessary it can make it easier to twist the bottle. Air pressure and science experiments 1. Remove the label from the bottle.

It s a hands on science two for one. Squeezing the bottle raises the pressure and the temperature. 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. The invisible air pressure around us is always changing but try explaining that to the tot lot.

Sick science is a registered trademark of steve spangler inc. 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. Changing air pressure is the source of the lift off but make sure you have an adult helping you with this activity. This is why submarines and deep sea diving suits have to be so strong to avoid being crushed.

Using the twist method 1. This allows more water vapor to evaporate.
