The COLLAPSING Can O_O

As you know, there is air pressure all around us and we barely even notice it every day. An amazing fact: the air pressure is large enough to crush a soda can!!! This is the collapsing can lab. The materials needed include an empty aluminum soda can, a 2/3 liter saucepan and kitchen tongs. After filling the saucepan with cold water, I put 15 ml of water into the soda can, then heated it over a stove. When the water starts to boil, a cloud of condensed vapor escapes quickly from the opening in the can. The can is left to boil for about 30 more seconds. Then immediately, I used the tongs to grasp the can and then with the flick of the wrist, the can is inverted and dipped into the water pan. The result: a very loud POP! The soda can collapses instantaneously. The cause for this effect is absolutely an immense amount of air pressure. The air pressure builds simultaneously when heated, thus air escapes out of the can. But when the water boils, an enormous amount starts to build up again. And when it is turned over, the air has nowhere else to go except for the top, thus, causing the soda can to collapse immediately. Air pressure is such an amazing feature of our world. It occurs everyday of our daily lives. Well, I hope that you enjoyed reading about air pressure, and wat a large amount of it would to an object. This was The COLLAPSING Can Lab.
