Working Principle of Crazy Party Horns :

In this Experiment, you pour liquid nitrogen and hot water into the soda bottles. The hot water converts liquid nitrogen into gas and comes out in the form of steam.

When you place a party horn on the mouth of the bottle the pressure of the steam unrolls the horn and makes them blow the sound.
