My tool is to fix the problem of zero gravity. Microgravity is where the gravity in space is at a very minimum so stuff just floats away because no one or nothing has any weight. The challenge of this is that tools float away so my challenge is to make an useful tool and won’t float away. My tool is a hammer with a chain coming off of the end to attach to their spacesuit. The chain coming of the end has a little slot at the end to put on the spacesuit. The directions for the astronauts is to slip the little hole at the end of the chain into the metal bib.
