My space tool is called 0-Gravity climber. With this tool you are able to pull yourself up with any magnetic metal. The tool is comprised of PLA plastic and a magnet, to be inserted and glued in the bottom indentation of the tool. How to use it: when in the space station there is 0-gravity. With this tool you are able to climb around the space station without touching anything other than the space tool. I watched a few videos and realized that all of the astronauts were holding onto various items attached to the walls. This led me to believe that they needed something for climbing around the space station in zero gravity.
