For this experiment you will need: a glass, a sheet of paper, water
The glass must be filled with water and covered with a piece of paper, so that the paper is tight to the edge of the glass. Keeping the palm of your hand over the paper, the glass is turned upside down and the palm is removed. If you kept the air from entering the glass by the paper, this would stick to the glass and the water does not flow out. If the air entered into the glass, the experiment will not succeed!
