‘The Incredible Spill Not’ is a product from Edmond Scientific that uses the laws of physics to prevent liquids from spilling out of a cup. The molded plastic cup is attached to a flexible Mobius loop handle that, via centrifugal force, lateral force and a low center of gravity, keeps your beverage of choice contained while spinning it in a full loop. According to the manufacturer, it’s “guaranteed to turns heads and drop jaws!”
The video below demonstrates how this works. I’m no physicist, but it’s just fun to think of playing with my drink this way. The Incredible Spill Not is available to purchase here.
