Carol for Coca-Cola, Get a Free Soda

Coca-Cola(NEW YORK) -- A Coca-Cola vending machine is spreading Christmas cheer in Sweden one bottle at a time.  

Equipped with two microphones and a karaoke screen with lyrics, the “Sing for Me” machine at KTH — the Royal Institute of Technology in Stockholm — is accepting carols as payment for soda.  

The carols are produced by Karaokefabriken.

This isn’t the first time a Coca-Cola machine has accepted something other than money.  Last spring, a machine in Singapore gave free sodas to customers who gave it a hug.
