N2 - We provide an alternative approach to a problem posed in the article “Hourglass of Constant Weight” by Becker and Pöschel (Granul Matter 10(3):231–232, 2008. https://doi.org/10.1007/s10035-007-0081-z), i.e. 14 years ago. Our goal to return to this article after so much time is purely pedagogical. Although there is a slight and subtle inaccuracy in the derivation of equation (8) in the work of Becker and Pöschel, which we correct, we use this circumstance only to give a detailed pedagogical exposition of an excellent physical problem and to show the pedagogical usefulness of the concept of momentum flow when considering the mechanics of systems with variable mass.
