To help spread the holiday spirit, Coca-Cola has created a vending machine that dispenses free Coke in exchange for Christmas carols.
The ‘Sing For Me ‘machine—a cross between a vending and a karaoke machine—lets people select their favorite Christmas carol and sing along.
It even comes with a pair of built-in microphones and a video display for the lyrics.
Once the participants are done singing, the machine rewards them with free cans of Coke.
