True or False: Liquid oxygen should have a larger surface tension than liquid bromine (assuming T and P are the same for both liquids). False: Surface tension of liquids increase as Intermolecular Force strength increases. Both O2 and Br2 are non-polar molecules, and have only dispersion forces. Those dispersion forces are stronger for Br2, however, since it has many more electrons (70 vs. 16) than does O2.
There are several ways to make liquid oxygen. This one uses liquid nitrogen to cool oxygen from a gas into a liquid. If you have leftover liquid oxygen, the safest way to dispose of it is to pour it over a noncombustible surface and allow it to evaporate into the air.
