I wanted to create an Item disposal system, with lava, and decorate it.

When I threw the bundle, with golden apples inside, the bundle broke, and the items inside it were duplicated.

1. Build a construction, like the one reproduced in the attached image;

2. Put items inside a bundle;
3. Drop the bundle looking at the fance;

4. You'll get the double of the item you put inside the bundle.

Thanks for attention.

Regards
