So how does the paint and mosquito repellant get out of the can? It’s the “magic” of science.
Aerosol cans are based on a simple law of physics. When a gas is put under enough pressure, it liquefies, and when the pressure is removed from that liquid, it turns back into a gas. When the aerosol product is in the can, it is under pressure and in a liquid form. When it is released from the can, its surrounding pressure decreases and it turns into a gas.
Although we don’t recommend trying to break open an aerosol can so you can see the insides, it can be interesting to dissect one on paper. A can of spray paint, for example.
The Mystery of Aero”solved”
An aerosol can is actually a complex piece of machinery that helps deliver a steady, concentrated stream of whatever product you desire, from hairspray to antiseptics. Not only is the product an important and beneficial part of your life, but the packaging it comes in is significant as well. And now you know what exactly is going on inside that mysterious can. All of that physics is going on to ensure that you can enjoy some whipped cream on your pumpkin pie.
