Quick answer
- Soul sand under water makes an upward bubble column.
- A
Magma block under water makes a downward one. - The column needs to be full of water source blocks.
Bubble columns shoot you up or pull you down through water. They make quick, cheap elevators.

Building a water elevator
- Build a 1 by 1 tube out of glass or any block.
- Put soul sand at the bottom.
- Fill the tube with water source blocks. Plant Kelp up the tube and break it to turn flowing water into sources.
- Walk in and you shoot up.
Getting outPut a sign or a door at the exit to hold the water in, so you can step out at the top.
Going down
A magma block at the bottom pulls you down fast. Soul sand and magma side by side make a lift both ways.
AirUp columns refill your air. Down columns don't, and they pull boats under too.
Cheat sheet
