This glitch lets you easily duplicate any stackable item in Minecraft Bedrock 1.21.131 on all platforms, including Realms and multiplayer. By filling your inventory and carefully picking up a single extra item with a slight delay, you can double the stack instantly.

Full Guide:

This glitch allows you to duplicate any stackable item in Minecraft Bedrock 1.21.131 on all platforms, including MCPE, PS4/PS5, Xbox, Switch, and Windows 10. It works in singleplayer, Realms, and multiplayer servers.

Required Materials:

  • 35 random blocks (to fill your inventory)
  • Item to duplicate:
    • If stackable to 64: 65 items (1 extra)
    • If stackable to 16 (e.g., Ender Pearls): 17 items

Steps to perform the glitch:

  • Place all materials in your hotbar.
  • Open your inventory and fill all slots with random blocks except for one slot, leaving 1 extra item in that slot.
  • Throw the extra item on the ground and move away so you won’t pick it up immediately.
  • Reopen your inventory and fill the empty slot with another random block.
  • Stand on the item on the ground and open your inventory.
  • Pick up the full stack of items from the ground through inventory pickup.
  • Immediately press ESC to close inventory (slight delay of a few milliseconds is required).
  • Temporary result: the full stack disappears (success indicator), leaving 1 item in your hotbar.
  • Save & Quit to the main menu.
    • Singleplayer: re-enter immediately
    • Realms/servers: wait 1-2 minutes before re-entering

Result: Your single item in the hotbar becomes a full stack, and a new full stack appears in your inventory (e.g., 65 → 128 items).

Tips & Notes:

  • Timing is crucial: pick up the stack, wait a few milliseconds, then press ESC. Pressing too fast may fail.
  • Duplicated items are real and can be used freely. Excess items can be stored in a chest to reset.
  • No complex contraptions are needed; the glitch uses inventory lag.
