This bus shelter promotes McCain Ready Baked Jackets using smell and heat. The interactive ad's central feature is a 2-foot fiberglass potato that emits a baked potato scent and heat when passersby press a button. An additional gadget spits out coupons for the product.
Designboom reports that McCain worked with a scent lab for more than three months to get the fragrant ad just right. For another clever bus shelter, check out these interactive Evian ads.
