It's a heating coil and a fan in a plastic case designed to dry hair, what exactly can you invent or is the ping pong balls some kind of Dyson reference, look I put a ping pong ball in the end and the air moves differently causing it to dry faster. Can I get a job at IBM?
Now without resorting to any vulgarities they should have been suggesting women put their collective brilliance into sanitary towels because all I see on the TV are adverts telling me different one's are better so there's obviously some design flaw with them. (Maybe except the one's that allow you to rollerskate while listening to early 90's eurodance).
And maybe if every advert for cleaning products/cooking/shopping/washing and general fuckwittery didn't just have women in them then maybe the world would start to be a better place.
