This thing lets you put other things inside it! Lets say you make a container named Box , and you want to put a Toy in the Box. You type: 1. open box 2. put toy in box 3. close box And boom! It's in a closed box. Looking at the box will tell you what is in it. To get something from it, you: 1. open box 2. get toy from box 3. close box And boom! You are holding the toy again! This thing is nice for a fridge, drawrs, etc.
