[Interesting Fact] Ideal Conductor

Assalamulaikum..

Do you know that scientists began to conjuring up ideal forms on earth with HELIUM?

A scientist discovered that below -452F, when cooling mercury with liquid Helium, the system lost all electrical resistance and became ideal conductor.

According to The Dissapearing Spoon book (chapter 1: Geography is Destiny):
This would be sort of like cooling an iPod down to hundreds of degrees below zero and finding that the battery remained fully charged no matter how long or loud you played music, until infinity, as long as the Helium kept the circuitry cold.
Another fact regarding Helium is that when cooled down to -456F, Helium turn into superfluid.

Superfluid has zero viscosity, and also zero resistance to flow. In other words, PERFECT FLUIDNESS.

However,  if the system has no viscosity and no resistance to flow at all, our superfluid Helium actually act against gravity and flow against the direction of gravity. At the time, these were flabbergasting find (Kean, 2011).
