Isn’t it annoying when you are with friends at bar and they won’t get off their cell phones? This is why the southern Brazilian Polar Beer came up with a solution: the cell phone nullifier, a beer cooler that blocks mobiles signals. When Polar bottle slides into the cooler, all cell phones at that table will be blocked within a radius of about 1,5m. The campaign is a creation from Polar brand and Paim ad agency.
