Do you have people who always try and take you stuff and come in your house without asking? then this is the trap for you.
Step 1: What You Need
What you need for this trap is
1 House with double doors
2 blocks TNT
2 blocks gravel or sand
2 stone pressure plates
1 trapdoor (optional)
So right infront of your 2 doors dig down 17 blocks. Go back up and on the second to the top block place your TNT 2 blocks and place the 2 gravel or sand blocks on top of them.
Now place the 2 stone pressure plates on top of the gravel. It is not necessary to have iron doors but it makes more sense to have pressure plates if there are iron doors. So that no one suspects a thing.
Step 4: A Secret Way In
Now go a certain way away from your house (behind it is best) & now dig down 3 blocks and turn towards the house and dig a tunnel all the way until you are under the house. now dig up and place your ladders & your trapdoor and you are done.
Step 5: How It Works
How it works is your unwanted guest trying to go into your house steps on the pressure plate lighting the TNT making it fall then the gravel (or sand) having to abide by the laws of gravity falls and your unwanted guest with it if the fall does not kill them the TNT will. & the reason you built the tunnel was so when you go into the house so you won't set off the trap and die.
