Abstract: In an example, a spherical drinking vessel is providing. The spherical drinking vessel may include a curved sidewall having a first hemisphere-shaped section and a second remaining section. The second remaining section of the curved sidewall may define an opening for receiving a liquid. A first thickness of the curved sidewall at a point corresponding to a nadir of the first hemisphere-shaped section of the curved sidewall may be different than a different point on the first hemisphere-shaped section of the curved sidewall. In an example, the second thickness is greater than the first thickness.
