We discuss the popular question concerning the difference in weight between 1 kg of iron and 1 kg of feathers, by taking into account the non-trivial aspect of the semantic interpretation of 'weight' and the weighting procedure. The inclusion of air buoyancy makes the correct answer an interesting one. We describe and comment on the experimental setup needed to obtain such an answer.

Abstract
We discuss the popular question concerning the difference in weight between 1 kg of iron and 1 kg of feathers, by taking into account the non-trivial aspect of the semantic interpretation of 'weight' and the weighting procedure. The inclusion of air buoyancy makes the correct answer an interesting one. We describe and comment on the experimental setup needed to obtain such an answer.File in questo prodotto:
