This is how to prank your friends in minecraft. first you have to know where your friend lives. second make sure your friend is logged off. You need a pressure plate and a piece of TNT. open the door then dig a 2 block hole on the opposite side of the door place the tnt at the bottom of the hole. place a block on top of the TNT then put a pressure plate on that block. Finally just wait for your friend to trigger the trap and start laughing. :D goodbye - xTatertotx
