Science Projects based on Air Pressure

What is Air Pressure and how can you use it in a science project? As you know air is all around us. It tends to push against us at a standard pressure. This is measured as 14.7 psi. However what happens when the air pressure around us is disturbed?

Ever feel the wind blowing? That is a direct result of the air pressure getting disturbed. However the wind can not be controlled in a science project. So let us pick an easier test for air pressure. All kinds of motion is possible to manipulate if you decide to meddle with the pockets of air pressure around you.

For instance if you blow under a balloon it will rise and float away. This happens because the pocket of air pressure under it is disturbed. So once the balloon moves and the effect of your blowing ends it will float down to its new location and sit there till some thing else disturbs the air pressure around it.

A balloon is light and so is easily influenced with the slightest change of air pressure, but how about water? Can air pressure effects be tested on water? Of course they can. In fact there is one trick here which magicians use in their show. It is not really magic but the science of air pressure at work. Here’s a whole list of experiments based on air pressure for you to try out. Using stuff like bottles, cans and balloons you can test the air pressure in the atmosphere around you.
