What will happen if you submerge a ping pong ball into liquid nitrogen

Ping Pong Ball submerges into liquid nitrogen

Here we have a ping-pong ball immersed in liquid nitrogen, and as the air inside the ping-pong ball cools, it generates force to make the ball spin.

Before that we have punctured two holes, slightly in a diagonal direction, now we are going to take it out and see how it is going to behave.

You can see the gas coming out from the bottom portions, as it comes out it twirls the ping-pong ball around about the vertical axis.  The ball begins to spin, reaching thousands of revolutions per minute.
