If you want to know the ratios more precisely, you can measure the diameters with your caliper and cube those, if you then divide the larger number by the smaller, then you have found the ratio of the masses of the two balls, Ian.
I love the tad as a unit of measurement because it's so easy to divide by 2, whereas a smidgen can only be divided by 3 and a bit, and a bit is roughly ten tads. Sorry mate, I've lost the plot, not been following the argument so the best I can do is crack a joke so the algorithm thinks I'm taking part in this scientific debate. Has he been nominated for a Nobel prize yet? I'm hoping he wins a Darwen award. Try persuading him to make his own bungy rope.
I don't have scales able to weigh accurately for these light masses, the large ball is 22mm and the small 17mm. If you can work that out I'd be grateful!
