Healthy Messaging, Snuck Into Snacks...

Colgate and ad agency Y&R teamed up for this little gem: a hidden message on a popsicle stick which reveals itself once you're done with the treat. It's socially responsible for the message to be healthy, of course - in this case, a reminder to brush your teeth - but a more tantalizing prize might make the whole experience even more (dangerously?) addictive. Yeah, probably best to stick with oral hygiene.
