What is Superfluidity? It’s so SPOOKy! Superfluidity occurs when helium-4 gets to near absolute zero and it turns into a QUANTUM state where all the atoms behave like a wave. Why Does Helium Drip Through Containers? Quantum Tunneling: At near absolute zero, helium atoms can quantum tunnel through tiny imperfections or pores in the container’s walls. These pores, even if smaller than the helium atom’s size, become “passable” because quantum mechanics allows particles to exist on the other side of
