Test two more features from Chaos Cubed! Watch out for geysers – vertical bursts of sulfurous water – or they will send you flying. Unless that's what you want, of course! Then, try feeding a TNT block to a sulfur cube. What happens if you ignite it? Surely nothing too bad or chaotic, right? Find out in Bedrock beta & preview right now!

Chaos Cubed Features and Fixes

Geysers
