Why Does This Happen?

Charles’s Law says that for each 1-degree drop in temperature an ideal gas will drop at the same rate in volume. (I.e. it’s proportional). Liquid nitrogen is – 196 degrees Celsius and causes the air inside the balloon to reduce in volume, as the air inside the balloon drops in volume it exerts less pressure on the inside of the balloon, allowing the constant air pressure outside the balloon to ‘squash’ it.
