  We promote the teaching of mass functions as an integral part of an
interdisciplinary science education. Mass functions characterize the frequency
distributions of objects with different masses on all cosmic scales. We intend
to enhance experiential learning of this concept with a creative LEGO brick
experiment for a diverse student audience. To our surprise, the LEGO mass
function is not only qualitatively but also quantitatively comparable to mass
functions found across the Universe. We also discuss the relation between
gravitation and mass distributions as a possible explanation for the continuity
of the universal mass function.
