Just yawn and get a free coffee

The guys at Douwe Egberts have created a nice coffee dispenser which can detect if you’re yawning and then it given you a free coffee. Neat trick, great publicity stunt and an even better future for me, as a coffee drinker.

Yay for such inventions. Seen this video thanks to Vsauce 2 list of Mind Blow #72:

Coffee, coffee, coffee.
