ABSTRACT:
The present invention relates to a straw cup with variable lights, primarily comprising of a set of light-emitting diodes surrounding the inside of the cup's straw, a circuit controller board, and power switch; when the power is activated, the liquid inside the straw's cup refracts and directs light, increasing the variation and brilliance of the twinkling lights and thus further increasing the variation of the straw cup's multicolored lights.
