Gravity Affected Blocks Duplication

Gravity Affected Blocks like The Dragon Egg, Sand blocks, Concrete Powder,

Can be duplicated if they are placed above a big dripleaf that is activated by a lever

This will cause them to bounce up and down, making the dripleaf shake because of the 

force of the gravity affected block whilst supported by the lever's power emitted. Also may be

because the gravity affected block is changing to a falling block and the block itself. Also it will duplicate when you go to a different dimension.
