I choose to write about the corkscrew i think it is cool machine because i used it in job everyday to open wine . it is a simple machine, it is type of gear lever and screw machine. The corkscrew goes clockwise into the cork to lift the cork fro the wine bottle then, it goes counterclockwise to get the corkscrew out of the wine cork.

I like corkscrews because they are so simple, and yet they perform a task that would be impossible without them.
