Mythbusters test golf ball effect on real car

http://www.megavideo.com/v/PMB935S87b2d887aa31261214bac8bb33d8f3bfcIt’s almost like someone got their Top Gear in my Mythbusters lately. First the duct tape holding up a car, and now the ‘golf ball’ effect on mileage. So what exactly does happen when you cover a car with clay, and then dimple it like a golf ball?

You can watch the video and find out, or just scroll past the picture of the lovely Kari Byron. The car part is about 40 minutes in.

Yes. Apparently, covering your car in clay and dimpling it like a golf ball will result in a significant increase in gas mileage. Who would of thunk it? The real trick it to make sure the dimples are scaled up to the proper size. I could get into the science, but it’s easier to let Jamie and Adam tell you all about it.
