Nuclear Fusion

Originating from https://www.planetminecraft.com/data-pack/nuclear-fusion-6714094/ (by me), this datapack allows you to perform nuclear fusion with a beacon.

To perform :

Boil a water bucket in a furnace to get steam, smoke steam in a smoke for hydrogen, throw two pieces of hydrogen next to a beacon to create a huge explosion that creates a bottle of helium you can drink to levitate.
