Almost everybody hates how short your time underwater can be without torches. For those who want a much longer time under (but not infinite 
) there is da ta dummmm!!!!! Scuba gear! You craft it out of rubber hose and an air tank. It allows you to actually explore the underwater (or under lava, for the suicidal) realm!
Suggested recipes.

The Air tank will automatically fill up (slowly, and not fully) as you walk around on land.
To fully refill the tank, put it in a refilling unit.
