Trap

Today I will be doing a simple lava trap that is easily resetable and can be put on a delay for however long you need.

First, you need to make an obsidian prison. This can be done by making a 3x3 with a hole in the center. Then, build it really high.

Next, break the corners. After that, put a pressure plate that connects to a 2x1 piston door setup. The pistons must be pushing a block other that obsidian. Diamond works well. Test it. Step on the pressure plate, and the pistons should extend. Then, hook the piston to a dispenser at the top with redstone. A redstone signal can go 8 blocks until you place a repeater. The taller the tower, the more delay. Put lava for a quick reset or TNT for a messy one. Then, do /gamemode 0 outside of the chamber. Walk in and the pistons should shut, causing the player to be trapped inside. The lava should pour down, killing the player. Simply replace the lava with any non-flammable block to reset the trap.

I will be doing all my blogs in the latest version from now on. With mod reviews and stuff like that, I will say the version I'm in. Right now, as of 10/19/2014, that is 1.8.
