Helium 3

A very useful material for nuclear reactions.

Description
Helium 3 is an invisible liquid. You can detect it thanks to its status effect, which reduces the effects of gravity thus allowing you to jump higher and fall slower.

Extraction
Helium3 canisters can be obtained by putting Moondust in the Extraction Lab.

Naturally spawning Helium-3
It has a chance to be one of the layer of gas of a gas planet.

Otherwise you can find it on Metal Moons (but it will not appear on every single one). There are also sub-biomes and other main biomes where it occurs but is most plentiful on Lightless biome, Metal and Ice Moons. Helium 3 only appears underground in these cases.

Usage
Helium 3 is gathered with a matter manipulator with liquid collection enabled. It must be put in a Helium 3 Canister in order to be used.

Real Life
Helium-3 (He-3, also written as 3He) is a light, non-radioactive isotope of helium with two protons and one neutron, used for fusion reaction experiments.
