How To: TNT Traps

Traps can aid the player in combat without the player putting him or herself in danger, sometimes not even having to be there at all. Today I will be going over some more basic trap types, TNT to be precise. The formula for TNT is below. The sulfur can be found as a drop from creepers(or use INVedit...).

The first trap is the most basic trap. Nicknamed "The Landmine" it uses a pressure plate and a TNT to detect when someone walks over it and detonate.
They don't just have to be used this way. A second way in which it can be used is combined with another basic trap. Here I combine it with a pit filled with lava. Still, one of many options to bring down the mob.

Then I closed it up...

Look! Zombies and creepers! Whatever shall I do?

Explosives and lava generally do the trick..

Another way to use TNT is to rig it with redstone wire. Acquire redstone and make a lever(the formula is a stick on top and a stone on bottom for a lever) then once the target is in proximity to the mine, pull the lever, detonating the TNT.

Before.

After.

Be creative. Combine old traps with these, combining is what broadens our spectrum.
