What is better than a convertible on a hot summer day? A convertible hot tub car, of course. Google recently commissioned YouTube sensation Colin Furze to use products from its advertisers to create something truly inventive. Inspired by similar projects, Furze designed and built a drivable hot tub car with a built-in grill. This 1989 BMW E30 convertible, clad in artificial grass, features two leaf blowers for extra bubbles and is the epitome of summertime silliness. Who knew advertising could be so much fun?
