Rubber Balloons, Buoyancy and the Weight of Air: A Look Inside
Calza, G.; Gratton, L. M.; Lopez-Arias, T.; Oss, S.
Physics Education, v44 n1 p91-95 Jan 2009
We discuss three methods of measuring the density of air most commonly used in a teaching context. Emphasis is put on the advantages and/or difficulties of each method. In particular, we show that the 'rubber balloon' method can still be performed with meaningful physical insight, but it requires a very careful approach. (Contains 4 figures and 3 tables.)
