Britvic has installed vending machines across the UK which dispenses free drinks to those who can prove their intelligence via a series of tests
The “smart” vending machines, which promote a brand of flavoured spring water called Juicy Drench, have touch-screens programmed with games that test mental agility. The idea is to reinforce the message that our brains perform best when they are hydrated.
Although presumably that means that you need to have drunk a Juicy Drench before playing in order to then win a free drink.
Most of the tests — which you can try out online — are a matter of simple maths, spot the difference, or spatial awareness. The vending machines will be installed in UK cities including London, Manchester, Bristol and Birmingham this month.
This is the latest in a series of vending machine innovations. Last month Wired.co.uk reported on a German publishing company Hamburger Automatenverlag (Hamburg Automatic Publishing) that adapted old cigarette vending machines to sell books instead of cigarettes at various locations in Hamburg.
Meanwhile in June, Unilever announced the launch of vending machines which reward consumers that smile, through the use of face-reading technology, and a Japanese vending machine company began trialling machines that can read the user’s age and gender.
