What would happen if you put these cute balloon animals into liquid nitrogen?

The first thing you might expect is a big KABOOM, but instead something unexpected happens.

          When you place balloon animals into a beaker of liquid nitrogen something very strange happens. In this MIT physics lab experiment these cute unfortunately won’t go out with a bang, but when they reemerge from the liquid nitrogen something amazing happens with each of the air-filled balloon animals.

     But how is this possible? Well this perfectly demonstrates the so-called ideal gas law that states that a drop in temperature with a fixed mass and external pressure will result in a smaller volume, and vice versa. In short this boils down to the fact that the volume of the balloon decreases by the low temperature due to the fact that the gas inside is cooled down.

Atoms and molecules are being slowed down which is causing the balloon to deflate

In this case the atoms and molecules that move and collide with the walls of the balloon are being slowed down and causing it to shrink. Furthermore, you can cause a similar effect the other way around by laying a balloon into the sun, this will speed op the atoms and molecules causing it to increase the pressure inside. Pretty amazing right?!
