Walkers (known as Lay's in the US) combined a snack vending machine with a bus stop and Twitter. The result? An interactive bus advertisement that dispenses a bag of potato chips when you sent it a tweet.

The unique vending machine was introduced as part of the Walkers 'Do Us a Flavor' promotion, which aims to narrow down the six finalists. In the running this year in the UK are flavors like: Steak Fajita, Chicken Curry, Pulled Pork in Sticky BBQ Sauce, Ranch Raccoon, Cheesy Beans on Toast and Hot Dog with Tomato Ketchup. The @Walkers_busstop will dispense 260 chip bags daily, encouraging the public to try out these unusual potato chip flavors and vote for the best ones online.
