Most people don't take a trip to the Amazon looking for publicity opportunities, but if you stumble on one you have to run with it, right? At Smarter Every Day, Destin and his rainforest guides took advantage of the complicated process leafcutter ants go through to forage for salt and got the ants to carry a little Smarter Every Day sign instead of the leaves they normally tote.

The ants all play a role in collecting, vetting and cleaning leaves, but they're happy to carry anything that's soaked in a "salty liquid". So rather than crying bitter internet tears, the guys on the shoot put a little bit of urine on each slip of paper, and the ants dutifully brought the signs into their colony. Life lessons.
