The Hydrokinetic Adjustable Wrench from ThinkGeek “uses advancements in technology to provide an infinitely adaptable tool — let you fiddle with twenty three different sizes of bolts and nuts.” Available now, priced at $29.95. Video after the break.

To adjust the Hydrokinetic Adjustable Wrench, just open the valve, fit around the nut or bolt of your choice, and push the gripper on the opposite end. It will compress the liquid which will, in turn, push the gripper on the end you want.
