Air takes up space Follow FizzicsEd 150 Science Experiments: Comments 10 You will need: One clear container filled with water Clear drinking glass Tissue paper Ping pong ball Copyright Instruction Video Instruction 1 Place the ping pong ball into the clear container filled with water. 2 Put the glass over the ping pong ball so that the ball sits inside the glass. 3 Push the glass down into the water, while it is still over the ball. The water level should rise around the glass and the ball should remain dry. 4 Remove the glass from the water. 5 Scrunch some paper into a ballput it into the glass. 6 Again place the glass, upside-down into the water and push down. The tissue paper should not get wet. Why? 7 School science visits since 2004! – Curriculum-linked & award-winning incursions. – Over 40 primary & high school programs to choose from. – Designed by experienced educators. – Over 2 million students reached. – Face to face incursions & online programs available. – Early learning centre visits too! 8 Online courses for teachers & parents – Help students learn how science really works 9 Get the Unit of Work on Pressure here! Want to dive into air pressure? Get the 60-minute video + PDFs + curriculum links for your class here! Why Does This Happen? Air takes up space. It cannot get easier than this! The pressure exerted by the air inside the glasses allows the air to exclude the water and the ping pong ball. Using the tissue just helps to show that air, not water, is trapped inside the glass. You would have noticed the water level rise within the container as you pushed the glass down. This is due to displacement, whereby the water is pushed out of the way by the air inside the glass. The same idea is applied when it comes to air locks in deep-sea diving bells. As long the air pressure is greater than the water pressure, the water will not enter the diving bell.
