Hopper

A hopper is a low-capacity storage block that can be used to collect item entities directly above it, as well as to transfer items into and out of other containers. A hopper can be locked with redstone power to stop it from moving items into or out of itself.

A hopper drops itself and its contents if mined with a pickaxe. Using any other item to mine a hopper drops only its contents.

A hopper can be crafted from a chest and 5 iron ingots.
