These constant width solids behave like spheres. This is possible because, independent of their peculiar shape, its diameter remains the same at any point. This can be demonstrated by positioning a flat object, such as a hardcover book, on top of the solid where it will then roll as if placed on a sphere. Furthermore, these wonky shapes don\u2019t roll away.
\nThe shape is based upon a revolution of the Reuleaux triangle.<\/p>\n

The attached booklet describes some of its applications, such as the Wankel engine that uses a rotary design or the drill bit that makes square holes.
\nSold in sets of 3 pieces.<\/p>\n<\/div>
