Exhaust Air Jack

For those like me who never know where to position the jack this is a perfect emergency tool to have in the trunk. Using the car's own exhaust to inflate, the air jack can lift a thrree ton vehilce 18 inches and stay inflated for up to 45 minutes. Don't toss out that AAA card yet, though, if your battery's dead your car won't inflate anything. Still, this is a darn useful contraption for the automotively inept. |via BookofJoe|
