Sponge can currently only be obtained in creative mode or by inventory editing.
A wet sponge can be dried in a furnace making the sponge reusable. If a bucket is placed in the fuel slot after the fuel is used up, including if the fuel was lava in a bucket, the water will drain into the bucket. This is currently the only way to get the water back.
Sponges have no use but decoration.
Sponges will absorb a 5×5×5 area of water around themselves in a ‘sphere’. The sponge must be directly touching a water source to absorb water, and will only absorb water connected to an adjacent water block touching the sponge. They are useful for clearing large areas of water, although the finite amount of sponge in each ocean monument means that they need to be placed carefully. When a sponge absorbs water, it will convert to a wet sponge, which is darker, drips water, and is unable to soak up any more water. Wet sponges can be dried in a furnace. The most efficient way to use sponge is to start at the top and go down; sponges placed at the bottom will just result in water flooding the cleared area.

|0.0.18a_02||Sponge block test.|
|0.0.19a||Sponge block added. The sponge was a temporary fix to stop water from flooding until finite water was implemented. It soaked up water in a 5x5x5 area around it. Sponges do not need light to survive, and do not decay (sponges used to decay in the implementation of the 0.0.19a update, but this was changed within 50 minutes of the release). It was also used as yellow for pixel art before yellow wool was introduced.|
|A sponge can be hidden in walls, floors, etc. as a defense against griefers. This can confuse and slow them down when attempting to flood an underground development, leaving more time for them to be caught and stopped.|
|0.0.19a_06||Sponges no longer decay.|
|Sponges became non-functional and available only by inventory editing.|
|A sponge can be used as a redstone object for updating blocks. If you place a sponge next to a block that needs to be updated, then remove the sponge, all blocks within a 5x5x5 range will be updated. This can be very useful for redstone builds using the BUD (Block Update Detector) switch.|
|1.8||The sponge is available in Creative Mode, but it doesn't function.|
|1.1||12w07a||Sponge blocks can no longer be used as a redstone tool.|
|June 8, 2014||Jeb tweeted that the ability to erase water blocks will be returned to the sponge. This also shows that they have a new texture. It is also seen that the sponge changes colour once it has absorbed water.|
|1.8||14w25a||Sponges have a new texture (), can absorb water again, and are obtainable in Survival. A sponge turns into a wet sponge when it soaks up water.|
