In order to brighten up the darkest of winter days, heating company Vaillant toured a smile-activated vending machine in various locations across the UK.

The stunt was part of what the brand calls 'Warmth Week,' which was developed to draw people out of the sadness that often comes with Blue Monday, cold weather and dark winter days. The smile-powered vending machines were designed to give out hot drinks like coffee or hot chocolate when a smile was detected. These fun stations were accompanied by brand representatives who gave out snugs to keep off the winter chill, as well as other complimentary goods like warmth kits.

For those who couldn't make it out to try out one of these smile-activated machines, Vaillant also designed a Facebook app that gives out warmth ratings in order to determine the hottest or coldest spots in the UK.
