HowTo: Build a Parasitic Bike Pump That Steals Air From Car Tires

Aleksi of Instructables has a genius idea. Bike tires out of air? Not a problem. That big old car down the street has some air to spare. Just insert Aleksi's pilfering emergency bike pump into any random car tire (make sure you're out of eyeshot, a look-out may be necessary) and siphon away.

Hah, what an #$%@!+* move.

That's Awesome!!!

Ok, but given that bike tires should be inflated to higher pressure than car tires, you would probably lose air to the car unless your tires were nearly flat.

Should be a punishable offense.
