MINECRAFT ADVICE
How to duplicate:
This helps if you have diamonds and you want more.
STEP 1: Put the item you want to duplicate in a chest, (remember it has to be the only thing in the chest).
STEP2: Wait 2 seconds and take the item out.
STEP 3: Wait twelve seconds then log out of he world. (Remember to not move and stand in front of the chest)
STEP 4: Look in the chest.
STEP 5: Enjoy!
