What does it say about my life’s degree of happening-ness that the high point of my day so far has been discovering these color-changing light-up drink coasters that you can buy online? I am not quite sure how to answer that question, but check these things out! You put a drink on it and it lights up, and then changes color! OMG! Party! I need to own them. Each coaster measures 3 ¾ inches square and sells for $23.95 per set of four. Available to own now by visiting Amazon at This Link.
