Here is an interesting experiment that shows the power of air and its ability to move things. A simple can with some water starts moving and turning vigorously when it starts to heat up. This is because the water in gets starts getting converted into water vapor. The water vapor tries to escape out of the two opposite holes in the can. It thus exerts pressure and makes the can turn vigorously! This is how steam engines are used to turn turbines ..Enjoy watching the mini engine here!
