It can be done using Nitrous Oxide, Diflouroethane, Xenon, Sulfur Hexaflouride, or any inert gas that is heavier than air.  Many different gases will work to produce this effect, but some can kill you or cause other negative reactions within the body.  If you are going to attempt this, I would recommend using Xenon which is a safe, inert, noble gas, but still runs risks due to the gas density displacing oxygen in the lungs.  Sulfur hexafluoride is slightly easier to obtain from universities with strong electrical engineering or research departments, but you still run the same risk.
