Duplication glitch using shulker boxes and dye

How to duplicate a shulker box using just dye (works best on a laggier server like a realm)

1. Grab a shulker box and fill it with anything you want to duplicate, and also grab a dye (to do this you will need an open slot in your hot bar)

2. Place the shulker box (I found it works best against a wall)

3. Break the shulker box

4. When the shulker box is broken and floating on the ground as an entity, spam the place button

5. You should end up picking up the shulker box and placing it, along with getting a fake one in your hand (the fake one disappears if you try to place it, so don’t place it)

6. Next dye it any color using the inventory crafting table (you should quickly see the dyed box go to an open slot in your hot bar then disappear)

7. Go to the slot that the dyed box went to and click the place button

8. You should now have your original box and the dyed box placed down (you will also have another fake box that disappears if you try to place it)

9. Open the dyed box and it should have the same items as the original
