Soul_Sand has a bunch of uses. The main one being that it slows you down. But did you know that while standing on Soul Sand you actually sink into the ground a little? Because of this, if there is a block in front of you 3 blocks off the ground and Soul Sand in front of it, you will be unable to pass. This can be a cool way to make some traps.
