Helium becomes superfluid and displays amazing properties.

To address all the comments about helium "running out": Most helium on earth is the result of radioactive decay (alpha particle emission and electron capture) over a very long period of time and is captured in the earth's lithosphere (crust). As such, the helium reserves on earth are finite. The main method of helium extraction is distillation from natural gas which contains up to 7% helium. Worldwide reserves and resources of helium are abundant and at the current rate of extraction will last several centuries.
