Grown-Up Curb Jumper

Ever seen a small child lovingly holding the hands of their parents as the three of them walk down the street? And every once in a while to the great delight of the child the parents will lift him into the air, with the kid laughing and swinging his feet like that's the best thing ever?

This invention will do just that, almost. A large aluminum frame with motorized wheels automatically keep up with you as you walk down the street. On each side is a fake hand that you hold onto as you walk. Whenever a curb or puddle is sensed and, of course, at random times, the fake hands, which are attached to the frame with springs or hydraulics, will gently tug your hands in warning and then lift you up, so you can squeal in delight and flail your legs around as if you were five years old again. Can be set to your weight so you aren't flung into the local deli window.
