The aim of this experiment is to prove the existence of air pressure.
To carry out this experiment, you need the following things: a cup, some water, a piece of paper. When all these things are ready, we can start the experiment. First of all, we must fill a cup with water .Then put a piece of paper on the cup. At last, turn over the cup.
After that an amazing thing will happen – the water is still in the cup. In the end, we can easily arrive at a conclusion that it is air pressure around us that hold the water in the cup.
