this tool will have a substance like glue to fix a astronauts visor it has a rotating grip so the astronaut in space can fix it there and now. one day this tool could save a astronauts life.The design i want is a big grip. A big sack to hold the substance. It is unique because as far i know no astronaut has ever been damaged in space. So their visor could get damaged in space so why don't we prepare to succeed before we prepare to fail.
