Building Your Bubble Elevator: Step-by-Step
A bubble elevator in Minecraft uses soul sand or magma blocks to create water currents that push you up or down. Soul sand creates upward bubbles, while magma blocks pull you downward.
Materials You’ll Need
- Soul sand (for upward elevator) or magma blocks (for downward)
- Glass blocks or any solid building material
- Water buckets
- Kelp (optional but recommended)
- Signs or doors
Construction Process
Step 1: Build the shaft
Create a 3×3 hollow tower using glass or your preferred blocks. Make it as tall as needed, leaving the center column empty for water.
Step 2: Place the bubble source
At the bottom of your shaft, place soul sand for an upward elevator or magma blocks for a downward one. The bubble source must be at the very bottom.
Step 3: Add water source blocks
Fill the entire shaft with water from top to bottom. Every block of the central column needs to be a water source block, not just flowing water.
Step 4: Create source blocks with kelp
Place kelp from bottom to top of your water column, then break it all. This converts every water block into a proper source block, ensuring your bubbles work correctly.
Step 5: Add entry and exit points
Use signs or doors at the bottom and top to create air pockets where players can enter and exit safely.
Pro Tips for Better Elevators
Make your elevator 2×2 instead of 1×1 for easier entry. Add multiple soul sand blocks at the bottom for stronger upward current. Consider building both up and down elevators side by side for convenience.
The key to a working bubble elevator is ensuring every water block is a source block – flowing water won’t create the bubble effect you need.

TL;DR
Build a bubble elevator using soul sand (upward) or magma blocks (downward) at the bottom of a water-filled shaft. Use kelp to convert all water into source blocks for proper bubble generation.
