One of the many memorable presentations at the 2010 Gathering for Gardner was that by Kenichi Miura. In it he reported about a fun idea of his that Martin Gardner would have loved to have heard about: a water wheel with buckets in the shape of Reuleaux triangles; Figure 1 is an example. In this water wheel water is being added from the top. This water then drains out of the buckets on the ways down, through holes in the sides facing us (not shown). This water wheel has the remarkable property that, as the wheel turns, any two adjacent buckets always touch in a single point while maintaining their downward orientation.
