Two for demonstrating and experimenting with various tidal effects are presented. The first takes advantage of the approximately inverse‐square nature of the force law for magnetic poles and exhibits symmetric tidal bulges on opposite sides of the planet, analogous to the of the earth. The second demonstration apparatus is a realization of the ‘‘rubber sheet’’ geometry analogy that is often used to potential wells of massive bodies in space. By rolling various objects on the of a stretched cloth one can effectively demonstrate tidal bulges, the Roche limit, and other well‐known astrophysical phenomena.
