This is a funny and easy Minecraft trick
Step 1: Getting Started
First you want to make a fake tree.
Step 2: Here Comes the BOOM
Make a 6 our 7 block deep hole.
Step 3: Tnt
Then you want to Put TNT on the bottom then cover it up, next put a pressure plate and cover it up.
Step 4: BOOM BOOM
Now it should look like this from the top. Then type in the command /gamemode 0. Then let some one on and they should brake the tree and then... kaboom!
Step 5: The End
Hope you had fun! Bye!
