Here’s an interesting, though gimmicky ad campaign that’s arrived just in time for the Super Bowl. Tostitos has created a limited edition bag that can tell if you’ve been drinking. The bag turns green if you’re in the clear, otherwise if it detects alcohol on your breath, it will turn red with the message, “Don’t drink and drive.” It will then also display a promo code good for $10 off an Uber, complete with near field technology to let you tap your phone to the bag call the Uber if you’re really that hammered. (Now that’s actually pretty cool). The catch is the bag cannot detect your level of intoxication, just that you’ve been drinking, so it’s really not a substitute for a breathalyzer or, more simply, just keeping track of how many drinks you’ve had. Hit the jump for a somewhat overly dramatic promotional video for the Tostitos Party Safe bag (yes, that’s really what it’s called).
