Soul sand is a unique block found in the game Minecraft. It has a dark brown color and is often located in the Nether, a dangerous dimension filled with various challenges. When players walk on soul sand, they move more slowly than on regular blocks, making it a strategic element in gameplay. Additionally, soul sand has a special property that allows it to create bubbles when placed underwater. These bubbles can help players rise to the surface quickly. Soul sand is also used to craft soul torches and soul lanterns, which provide light and add a spooky atmosphere to builds.
