USING AIR TO CRUSH AN ALUMINIUM CAN!!!

Let's take the help of air to crush a aluminum can!!!


Materials:


Aluminum can

Saucepan

Kitchen toungs

Water

Cold water

Instructions

Fill the saucepan with cold water.

Now fill the can with 2-3 teaspoon of room temperature water.

Heat the can until the water inside starts to boil. ( You would see vapour cloud when the water starts to boil)

Let the water boil for 30 seconds.

After 30 seconds quickly grab the can with the KITCHEN TOUNGES and put it in the saucepan upside down



What is happening???



The water vapor created from heating the can pushed air out of the can. When the can is inverted and placed into the cold water, the water vapor in the can condenses quickly. Like the egg in the bottle experiment, the pressure in the can decreases quickly. The outside pressure is much higher than inside which causes the can to collapse!
