The SpillNot® is an elegant solution to the ubiquitous problem of spills while carrying an open beverage such as a mug of coffee or tea. A simple hanging saucer consisting of the base and a webbing loop handle, it is useful, novel,… and fun. Based on the fundamental laws of physics, it is astonishingly effective.

The SpillNot allows a single open beverage in a wide variety of container shapes and sizes to be carried easily for long distances with amazingly little risk of spilling and without excessive concentration to avoid spills. The non-intuitive nature of the solution is so striking that in action, the invention is fascinating to observe. It’s so simple, yet history has no record of a SpillNot before this!

The SpillNot provides entertainment and a challenge if desired. For example, some confidence and skill are required to perform tricks (best attempted outdoors in an open area with a small plastic cup of water) like flipping it upside down. However, when used simply to go from point A to point B with a beverage, it is often easier than carrying a full mug. It could also be a social ice-breaker by providing entertainment and an interesting topic for discussion, as the underlying physics are not trivial.
