Mentos Tongue Twister was aired on LCD screens in elevators and on the outside of buildings.Two bored clerks are mindlessly chewing gum at the office. One guy starts chewing fanatically then sticks out his tongue. Tadah! The gum is shaped like a bone! His friend is not so impressed so he chews another silly shape.Not to be outdone, the other guy starts chewing then unfurls his tongue. Tadah! The gum is chewed into an intricate 3-layer Italian fountain complete with green liquid squirting in sync with the music.
