|

Hoppers interact with containers the following way:
|
|
• Furnaces: Hoppers from above will put items into the source slot. Hoppers from below take items from the output slot. They also take items from the fuel slot when they can't be used as a fuel. Sideway hoppers put items into the fuel slot
|

• Ender chests: Hoppers don't interact with ender chests
|
|
• Other containers: Hoppers interact with them normally]],
