Demonstrating the Crushing Power of Atmospheric Pressure in Less than a Second

Demonstrating the Crushing Power of Atmospheric Pressure in Less than a Second

In this experiment, we are going to further demonstrate the power of atmospheric pressure, in less than a second.

Atmospheric pressure is caused, literally by the weight of the air above you. To understand it better, use the analogy of water pressure, as you go deeper into water you have the equivalent weight of the water above your head pressing down on you. The deeper you go the more water above you, the greater the pressure. So it is with air pressure; the lower down you are the more air above you the greater the pressure. The higher you are, the lower the pressure.

Experiments you can do at home

Welcome to Dr Hal's Backyard Science, experiments you can try at home. These are experiments that you can try in your garden or house with parental permission and supervision. Each of them comes with some health and safety instructions that an adult must read. The text is reproduced by kind permission of Education in Chemistry a journal of the Royal Society of Chemistry.
