New Dupe Method?
Idk if this dupe method still works (haven't tried in a long time), but here's how to do it.
Put an item inside a dispenser and make it shoot into a hopper, connect the hopper to a chest and when the item gets to the chest break it (must be done with perfect timing)

Anyone who found a duping method probably will never share it due to it being patched once released to the public.
Look up "jamea" on youtube. Has about 8k subs and is constantly improving this method.
