Calvin's dad knows all! Problem solved :)

On a side note, the answer to how much the sky weighs is, of course, complete rubbish. It may have a mass of 570,000,000,000,000 adult Indian elephants but its weight is measured in Newtons, not in Kg or lbs. Since the sky has a thickness and therefore the strength of gravity varies across its height, calculating the weight of the sky is a lot trickier and would have to account for the macro and micro-variations in gravity and the different gases at different heights as well as the variations in density at different altitudes from the surface of the earth to the edge of the atmosphere where "air" stops and space starts (another thing that not everyone agrees on).

Totally agree - he gave the mass, not the weight.

Whereas the air pressure one is a much more accurate way of doing it.

Oh yes, that's a good answer. Though I think the best answer would have included an explanation how air weighs anything at all, when most people don't really get that, if they think in terms of bathroom scales.
