well here's a furniture idea:

For a fridge you can put a dropper in the wall, fill it with food,then cover it with two vertical iron blocks. Place a iron door on the blocks and place a lever either by the side of the "fridge" or on top of it. When you pull the lever, the iron door will open and whatever is the the dropper will come out. You can also use a button with this idea.

Hope i helped :)

yeah i can help but help with what

Maybe state the actual problem so others know what you need help with exactly. You need to add more details. Help with what? Where? Why? When? How?
