car, transportation, egg Answered
Hi, i have to build a toy car or something like it, powered by rubber bands so its no problem, the thing is that it has to travel 31ft on a straight line, and then stop at 31ft and drop an egg. the egg must survive the fall from the car... Any ideas??? I'd consider using some type of braking mechanism. A string wrapped from a front axle to a rear axle would make a great brake. It would work kind of like a cassette tape; winding from one side to the other, and stopping when it's completely transferred form one to the other.
