A Balloon Makes for a Perfect Parking Sensor [Video]
Parking sensors have become very complex and thus cost a lot more than ever, plus they're too mainstream. But what if you payed $500 for a jalopy from the scrap heap. What if it runs on only two cylinder and you still love it?
All you need is a balloon and a place to tie it to the middle of the rear bumper. All you do is just reverse into a brick wall and wait until the balloon pops. With shapes varying from dogs to Superman, there are limitless customization options. Just don't attach too many or that jalopy will fly away.
