I loved this episode. I was completely shocked it worked and was so wrong on why it worked. My thought was dimples on a golf ball kept it stable in the air, like rifling in a gun barrel. But dimples make a golf ball fly twice a far due to decreased drag caused by the increased turbulence (http://wings.avkids.com/Book...). I guess this is another example where introducing noise makes things work better. The Mythbusters tested if this approach would work on a car. It did! There was an 11% increase in gas mileage when driving the dimpled car. Now I'm assuming car engineers know this and haven't designed a car like this because they test marketed the idea in a mall somewhere and people hated it. Time to change. I think this kind of car would be a counter cultural badge of honor and would really be popular, especially in the younger demo. - Todd Hoff

Apparently hexagons result in a lower drag than the even round dimples, that would be cool to try. - Todd Hoff

dimples are awesome, no matter where they might appear. - Morgan Haley

time to try this on aircraft. - Joe Silence is not dead

Cool, but I'd hate to have to wash and wax that. :) - ha3rvey (needs soup)

Experimental aircraft that have been declassified recently have a similar less indented pattern. I used to think it was only for radar evasion ? - Eric Logan

Cool Eric. - Todd Hoff

This is really awesome - Chieze Okoye
