This is how you make a game out of physics.
This particular video highlights the use of an air vortex created because of a circular exit hole for the air.
But how does the air come out in the first place?
That is air pressure.
When the air is compressed in the box (By hitting the sides), the air pressure in the box is high. This forces the air out through the hole in the box.
When the air comes out, Bernoulli's principle states that the high velocity will create a low air pressure, eventually creating the circular 'doughnut' shape because the air is moving around itself.
