The Screw Brush is a combination of a screw driver and toothbrush. It is very easy to stick into something. It floats very slowly.
The Screw Brush has an extender, so that astronauts can screw objects up to six feet away. If you have to fix something at night, the Screw Brush will help. The astronauts can use it to brush their teeth and fix things. I think this tool is very cool.
