Buddy Cup: the glass automatically adds to friends on Facebook everyone with whom you are clinking

How does this usually happen? You pull out a smartphone, unlock it for a long time (especially if the party is already in full swing), tiringly figure out the name of the person and how it is spelled accurately, log in to Facebook, search, compare with reality and then add to friends. Tiring, isn't it?

The Brazilian branch of Budweiser decided to simplify the whole procedure by creating the Buddy Cup. These are glasses (presumably for beer), and when you clink glasses with them, you automatically add a drinking buddy to your friends in a social network. The glass is tied to your account via a QR code on the bottom, and the LED indicator on the side serves to confirm “friendship.”
