Drinking together has important roles in human relationships and social interactions. In this paper, we suggest drinking as an implicit communication channel and an enhancer of communications. We present Lover's Cups as drinking-together interfaces that promote sharing the drinking time with someone you care about. The drinking interfaces are a pair of cups with a wireless connection that communicate with each other and amplify the social aspect of drinking behavior.
