Here's a vending machine that everyone can get behind. Coffee company Douwe Egberts designed a new vending machine that dispenses coffee when you yawn. 
The vending machine currently resides at the O.R. Tambo International Airport in Johannesburg. It knows when you yawn with the help of facial recognition software, which then triggers a fresh (and free) pour of coffee.
