#Helium π§΅ is super interesting!
Itβs an inert gas, atomic weight 2, and is 24% by weight of the entire known universe!
Because itβs so light, we can only transport it in custom reinforced metal canisters, and even then it leaks rapidly.
Delays in shipping may mean complete loss of the helium - 6 weeks is about the longest you can get away with.
