How to duplicate things on minecraft

U see I only have 1 gold bar NO MORE

Now I put this chest from before U HAVE TO HAVE 1

Put ur item in ur chest

Now keep it in there and exit out of that world

Go back in and take the gold bar

Now walk away ATLEAST 15 blocks away from ur chest

I'm over here

Exit to home screen and double tap the button thing take minecraft away

Go back into minecraft u should spawn a few blocks away from where u exited for some reason i spawned right at my chest…

TA DA there u go

Oh btw this works on any kind of item I insist that u first use something that u don't need because tbh at first I used wood so use somthin simple
