Bubble Column Tweaks
by FugLong
Bubble Column Tweaks changes how fast entities move inside bubble columns created by magma blocks and soul sand, through a configuration file.
What it does
In vanilla Minecraft, magma blocks produce columns that drag entities downward while soul sand produces columns that lift them, each at a fixed speed. This mod lets a server owner set the maximum speed and the acceleration for each column type separately.
The mod works only on the server, so players join without installing anything. Clients need it only for single-player play, where the same settings apply. It is open source under the MIT License and is published for Fabric and Quilt, with the latest file 1.1.0 for 26.1.2, dated 2026-05-18. Its configuration accepts both a magma surface setting and the column settings, and the defaults match vanilla behavior.
Key features
Magma column pull speed
Sets the maximum downward speed and the acceleration rate for entities inside columns created by magma blocks.
Soul sand column push speed
Sets the maximum upward speed and the acceleration rate for entities inside columns created by soul sand.
Magma surface settings
Separate limits control the downward speed and acceleration of entities on the magma surface.
Signed value scheme
Negative values pull entities downward and positive values push them upward, with larger absolute numbers giving faster movement.

Use cases
Who it’s for: Server owners who run survival or adventure worlds and want bubble column travel to feel different from vanilla. Single-player players who want the same change can install it on the client too.
How it compares
Copper Grates Bubble is also server-side only and open source under the MIT License, but it is published for Fabric alone and covers 1.21 – 26.3. Bubble Column Tweaks runs on both Fabric and Quilt. Better Bubbles is client-side only and not open source, released under the Creative Commons Attribution Non Commercial Share Alike 4.0 license, for 1.21 – 1.21.1, so it changes what players see rather than how bubble columns move them.
