Air exerts Pressure

Zara, grade 1A student came up with an experiment to show how air exerts pressure by using an empty plastic bottle and water. She poked some holes at the bottom of the bottle and filled it with water till two thirds of its length. When she opened the lid, the water flowed out from the holes in tiny streams and when she secured the lid, the water did not flow out. By that, she concluded “Air exerts Pressure”. Kids were very excited to see the experiment and it was a wonderful experience for all of us.
