Fun air pressure experiment.
-You will need a cup completely full of water, two straws, and scissors.
-Put one straw in the water and cut it so that it sticks out of the water by only about 1/2 inch.
-Angle the straw upwards so that the air coming out of it passes right over the top of the straw in the cup. Keep blowing and blowing. This will make the air move faster over the top of the straw in the water. As a result, the air pressure above the straw in the water will decrease, and when there is less air pressure above the straw, what do you think will happen?
Try it and see 🙂
