UK drink brand Drench has introduced a new concept in vending machines: brain games. In cities across the UK through August and September, the brand's Smart Vendiing Machines will be challenging thirsty passersby to use their heads to win free drinks. Interactive touch screens on the machines feature 40 different games testing mental agility, in order to illustrate the idea that hydrated brains function better. Players will receive free bottles of Juicy Drench spring water for taking on the challenges.
Consumers who don't have access to the machines can also have a go at the games on the Drench site.
