Abstract
This invention provides a cup with twinkling light effects, primarily comprising an inner cup, an outer cup, and a light unit, with the lower half of the inner cup having a number of arched convex strips, and the base of which has diamond-facet of concave and convex cones. As a result, when the light unit at the base of the outer cup is activated, the effects of the arched convex strips and diamond facets cause the cup to produce numerous refractions of the light source, creating twinkling rays of light with dazzling variation.
