101 2 litre bottles of Diet Coke + 523 Methos mints = One cool science experiment
These videos are hosted by Revver, which is a consumer generated video site that includes ads and shares the revenue 50/50 with the video creator. In this case there is a Menthos ad at the end which almost summarises the whole essence of the mint.
See the current Menthos Ad which interestingly enough has a guy who sneezes and mistakingly shaves off a little hair from the guy. He ponders the repurcussions until his friend helps him come out clean.
Perspective: Consumers are freely trading their time to watch these videos, and in this case Menthos gets to communicate it’s product while benefiting from the viral aspects.
