This is a space art station. On the bottom, there is a container for a 4x6 piece of paper, with a snap on wall, so that the paper could not float away. On the top, there are two holders for the paper. On the top, there is space for seven sharpies. I put a holder for sharpies on the top, because if you had a liquid, such as paint, it would float away. It works by taking the lid off of the paper holder. You then slide the paper into the two paper holders. After, you take a marker from the marker holder. You then draw, and you can hang the drawing up, or put it back into the paper holder. This would be helpful in space, not because it is a tool, but because astronauts need a form of entertainment, and I think that drawing would be very fun.
