Item Duplication; diamond, emerald & more

Craftable items duplication by taking item out of dropper at time it is destroyed by tnt.

To duplicate,

1. build mechanism and place dropper and tnt as represented in pictures.

2. place any craftable item inside dropper

3. ignite tnt

4. redstone torch will light up at approx time when to pull item out of dropper

if done correctly, (sometimes takes numerous tries)two items will drop, the original and the duplicator block. this block can only occupy one inventory spot, in order to duplicate you must take block and craft it into diamonds. This block will remain for 5 minutes until it disappears allowing it to be crafted into hundreds of diamonds in that short time.
