Duplication glitch
First get a chest and the item(s)you want to duplicate
2. Place the chest, and then put the item(s) in the chest that you want to duplicate
3. Exit out of the world then re-enter the world
4. Take the item out of the chest and exit the chest! Put the item in your inventory
5. Count to 20 slowly
6. Then double click the home button, and slide the minecraft page up
7. Go back in minecraft and re-enter your world!
8. You should be spawned right next to your chest, now open the chest
The item you duplicated should be in the chest and inventory
You just duplicated your first item(s)
The rare part of this is that you can get your items duplicated so quickly!
In 1 minute with one diamond, you can get 8 diamonds

The scary part.... I've done this many times... And one time I was on a server with my friend and I was duplicating (he got kicked out everytime.) well we were talking of herobrine and I said "Herobrine....pfft...herobrine my butt"
Little did I know, that was a bad choice...
I got so addicted to duplication, that I was filthy rich with diamonds.... I had summoned herobrine!
I almost peed my lance cause I was so scared.... I came back on.... My house was distroyed, there was a hole bunch of nether reactor temples, and only one chest ful of diamonds

Duplicaters, be warned, do not make my mistake!
