Coca-Cola once created a special bottle — part of its “Friendly Twist” campaign — whose cap couldn’t be opened by one person alone 🥤🤝 The design forced two people to join their bottles and twist together before they could open either — turning a simple drink into a way to spark conversation and connection. The idea was tested on college campuses, especially aimed at freshmen, to help break the ice — creating spontaneous interactions among strangers who needed to cooperate just to enjoy a Coke.
