Helium
Why is helium so expensive? The price went up due to inflation!
When I think of a party I think balloons and not just balloons but balloons filled with helium.
Not so popular on earth but the moon is full of it. Here is a good reason to make the next party on moon.
If you thought that fluids always goes from high to low. Than Helium can mess with this concept. When you freeze helium to almost absolute zero then it will become a super fluidity. A phenomena that if you leave such fluid in glass it will rise over the edges of the glass and will spill over until there is nothing left in the glass.
The name Helium come from the Greek word Sun. Because it was discovered as a yellow light on the edge of the sun during total solar eclipse.
Next week we will party with Lithium
