If your pinewood derby car needs a not-so-complicated way to check its weight, look no further! This is an overly complex approach to determining if your car exceeds the weight limit. All you'll need is last year's perfectly weighted car at 5.0 oz. Place it next to the new car on a scale. If both cars hover in mid-air, your vehicles are equal (mostly). However, friction within the system may cause slight variations. This past weekend, my son's car tipped the scales at 5.05 oz compared to last year's model at 5.0 oz.
