Today I am going to show you how to make an exploding tree to confuse your friends with!

Step 1:
Find a nice big tree

Step 2: On the top of the trunk, place a redstone torch.


Step 3: Place a sticky piston above the torch so it goes out.


Step 4: Place tnt on the end of the piston and a redstone torch next to the block where where the tnt will be when the piston retracts.


Step 5: Place some tnt dotted around the tree where it cant explode unless triggered by another tnt.

Step 6: Cover up any traces of anything. You're now finished!

How it works: When a player breaks the trunk of the tree, torch 1 breaks causing the piston to retract.
Then torch 2 causes the tnt to ignite, causing the other tnt dotted around the tree to set off too!
