Hello. In this video I will show you,
how to duplicate any items in Minecraft. First you want to drop the items you want to duplicate.
Then save and quit to title. Now load the world again to pick up the items. After you have picked up the items,
you want to press alt and f4 at the same time to close the game. Now start Minecraft load up the world and the items you just picked up
