Sponges are one of the most incredible blocks in Minecraft that players can use to absorb water and dry different underwater structures or areas. Using a sponge to absorb water turns it into a wet sponge, which can later be smelted in various ways to then dry it again.
Sponges will absorb water present at a seven-block distance of it in any direction. There is a trick in Minecraft using which players can get a bucket of water while smelting a sponge in a furnace.
They can do this by placing an empty bucket in the fuel slot after the fuel has already started burning.
