Hopper Dupe (1.21.100 - Bedrock)
Dupe works by tricking the game into duplicating a stack of items in your inventory. 


1. Place Hopper A facing into Hopper B



2. Put a stack of items into a bundle (doesn't matter which color it is).
3. Place the Bundle inside of Hopper B.
4. Open Hopper A, and remove the Bundle right before it goes into Hopper B.
Note: You may have to keep trying! If you fail, remove the Bundle, and restart the process.
Tip: The 3rd frame is when you should do it (0.7s)

This works on all devices! Some people don't find success on console because they don't do it the right way.
