About 20% of the visible matter in the universe is pure Helium gas, but because it is so light and doesn't react chemically with anything, Helium gas escaped from Earth into space, when the solar system was young. So now Helium gas is quite rare here. Nonetheless Helium gas has multiple applications, from making balloons fly, to cooling things to extremely low temperatures with liquid helium. On the right picture is showed the ionized Helium gas. That is possible when the Helium gas is rarefied (or in low pressure atmosphere), using a high voltage transformer or simply using a Tesla Bulb for sale here.
