You go to the bus stop and what?!?! There's a giant potato jumping out at you. Then, ahh, the smell of a fresh oven-baked jacket potato. Talk about a truly multi-sensorial bus shelter ad that can wow you and make you hungry! The technology behind the scent releasing technology is pretty amazing....when a button is pressed, the fiberglass 3-D potato is heated to release the aroma. On top of that, it also dispenses a coupon for the McCain 5-minute ready potatoes. Oh you lucky straphangers in York, Manchester, London, Nottingham and Glasgow!
