On designing a tetrahedron-like shape that is only stable on one face.
"[I]n a preprint posted online yesterday, they have presented the first working physical model of the shape. [...] To work, it had to be engineered to a level of precision within one-tenth of a gram and one-tenth of a millimeter. But the final construction always flip-flops onto one face, exactly as it should."

Today, I learned that some football clubs are using Reuleaux tetrahedrons instead of spherical balls in training to improve goalkeepers' reflexes. https://en.wikipedia.org/wiki/Reuleaux_tetrahedron
