Getting people to clean up after their dogs in public places is never easy - just take a look at how many "land mines" are dotted around your nearest park. One internet company in Mexico however, has hit on a clever incentive to encourage people to scoop up after their pet. Dog walkers in Mexico City are now finding pet waste disposal bins showing up in some parks that activate a free wireless network for a set amount of time depending on the size of the "deposit."

The internet company, Terra, partnered with advertising agency, DDB Mexico, to get the devices installed in ten different parks around Mexico City and named the service "Poo Wi-Fi." These special bins are pretty straightforward: a dog owner drops a baggy of waste inside, the waste is weighed, and a timer is then activated with a number of minutes based on the weight received. More weight means more minutes. While the timer counts down, anyone in the park can enjoy free wireless connectivity. There are even hostesses nearby throughout the day with plastic bags on hand for any pet owner that needs one.

Besides promoting its own brand, Terra hopes this could encourage dog owners to be more mindful of their pet's messes. The bins don't have any way of sensing what's actually put in them, so really any garbage could be dropped inside for Wi-Fi minutes, but the company just sees that as a way to tidy up the parks even more. Exchanging Wi-Fi for feces might be a bizarre concept, but if it motivates people to keep their public spaces cleaner, it could prove to be a good method in the long run.
