May the Centripetal Force be With You - The SpillNot provides the ultimate solution for carrying cups of hot coffee and other beverages without ever having to worry about spilling them again. A simple hanging saucer consisting of a base and loop handle, the SpillNot is not only incredibly effective, but also fun to use. With the SpillNot, the liquid in the cup does not tend to spill or slosh, and the cup does not tend to slide when carried. This is because the loop handle is very flexible and therefore cannot deliver a lateral acceleration to the cup, which is usually what makes a beverage spill from an open container while carried. The fundamental concepts of Newtonian physics explain why this tray can be used to carry a full open beverage with no spills! For swinging a beverage, try a plastic cup outdoors - a little practice may be needed. Warning - There are limits. The SpillNot is science, not magic. If bumped, spillage may occur. Sudden movements and jerks may cause spills. Not for use with liquids that are hot enough to scald. Not for use in moving vehicles. Not recommended for moving vehicles. Not for children under 3 years of age.
