Get free coffee by yawning at the machine

SOUTH AFRICA - This coffee machine by a South African coffee company Douwe Egberts, dispenses free coffee when people yawn at it.

The machine located at O.R. Tambo International Airport is equipped with facial recognition software that is able to detect the exact moment of a yawn.

Once a yawn is detected, it starts to dispense a steaming cup of coffee for the tired person standing in front of it.

Dubbed as "Bye Bye Red Eye", the coffee machine has rewarded 210 yawns with aromatic cups of coffee.
