We all know the first noble gas is Helium. We know Helium as a gas for blowing up balloons. but most people don't know about the odd property oh Helium. Helium has two distinct states-one of which is borderline creepy. Helium turns into liquid at about 4.2 Kelvin(-268.95 degrees Celsius). But when is cooled further to below approximately 2 Kelvin, it can do things that other fluids can't, like dribble through molecule-thin cracks, climb up and over the sides of a dish and get motionless when it's container is spun. Now it no longer a mere liquid, it is the superfluid. It can flow without friction. Liquid Helium has been used as a cryogenic refrigerant, and in superconducting magnets such as those used in magnetic resonance imaging(MRI), nuclear magnetic resonance(NMR), Magnetoencephalography(EMG) and some experiments in physics.Antigravity Helium
