Male 1: There were more surprises ahead. In the 1930’s another strange phenomenon was observe at even lower temperatures. This rapidly evaporating liquid helium cools until at 2 degrees above absolute 0 and dramatic transformation takes place.
Suddenly you see that the bubbling stops and at the surface of the liquid helium is completely still. The temperature is actually being lowered even further now but nothing particular is happening. Well, this is one of the great phenomenons in 20th century physics. The liquid helium had turn into a super fluid which displays some really odd properties.
Male 2: Here, I have a beaker with an glaze ceramic bottom of ultra fine velocity.
Male 1: Ordinarily, this contain with tiny pores can hold liquid helium, but, the moment the helium turns into super fluid, it leeks through.
Male 2: We call this kind of flow, a super flow.
Male 1: Super fluid helium can do things we might have believe impossible it appears to defy gravity. A thin film can climb walls and escape its container; this is because a super fluid has zero viscosity. It can even produce a frictionless phantom, one that never stops flowing. Super fluidity and super conductivity were battling concepts for scientist, new radically theories when needed to explain them.
