Liquid Hydrogen

As shown in this picture, the element Nitrogen, when kept very cold, is a liquid. In this picture the liquid can be seen evaporating.

If conditions are just right, the element Hydrogen, which is normally a gas, becomes a liquid, just as Nitrogen does if the temperature is just right.
