I know it rocks but please do not steal it
It sometimes happens that people steal a glass from the bar as a reminder of the night out. Cider-maker Kopparberg has developed a solution for this problem. They protected their new glasses with a security system with ink. When the ‘thief is more than 100 meters away from the bar the ink will ‘explode’. The goal is not to punish people but to dissuade them from stealing the glass.
