On Valentine’s Day, millions of people in the United States say “I love you” with chocolate. But what makes Dove unique when it comes to love? We devised a new technique to make chocolate "speak" using a recording of a real couple declaring their love for one another, which was played back through a powerful speaker beneath a pool of melted chocolate. When the vibrations of the sound moved through the chocolate, it leaped into the air, creating a physical representation of true love. We captured the precise moment of the chocolate explosion on camera.
