Artificial circumzenithal and circumhorizontal arcs

Abstract
We revisit a water glass experiment often used to demonstrate a rainbow. On a closer look, it also turns out to be a rather close analogy of a different kind of atmospheric optics phenomenon altogether: The geometry may be used to faithfully reproduce the circumzenithal and the circumhorizontal halos, providing a missing practical demonstration experiment for those beautiful and common natural ice halo displays.
