Matt Strafuss, a technical instructor in MIT's Physics Department, demonstrates the ideal gas law. A drop in temperature with fixed mass and external pressure will result in a smaller volume, and vice-versa.

Liquid nitro is certainly cool to play with, however complete precaution must be administered while using it. Hospitals, medical labs and physicists take the help of dewars to store it. May be its time that chefs also start doing that.
