A quick lesson in helicopter physics (and some fun with lights at night)

(CBS News) SmarterEveryDay is back with a new video that explains a bit of the what and how behind helicopter physics in a way we can all understand and dig. Definitely check it out.

So after a nice long play with lights on an RC helicopter (and some very cool light paintings), we actually do learn a whole lot about how the blades of the helicopter determine flight and speed. Very, very cool stuff that has earned a big triple-rainbow salute from us here at The Feed, and which is why SmarterEveryDay has been featured here numerous times for their fun and educational videos (click to see others).
