This is a nice decoration piece for any minecraft house and works well for food storage too!
Step 1: Get the Blocks!!!
To make this fun simple redstone project all you need is an iron door, any expensive block (i prefer iron) a dispenser or dropper, a button, and some food!
Step 2: Place a Dispenser
Step 3: Add Your Expensive Block
Just plop your block on top of the dispenser like so! You will have to hold shift while placing it so that you actually place the block instead of accessing the dispensers interface.
Step 4: Add the Iron Door
Stand a little behind the two blocks like this so that the door is connected to the dispenser and top block
Step 5: Add a Button and Food!
Throw a button on the side a d fill the dispenser up!
Step 6: Get Your Food
When you hit the button the door will fly open and a piece of food will pop out!
