So, just cause it's the sweet space between Christmas and New Year's doesn't mean you can't still learn new, cool things — like physics.

Today's coolness is the Magnus effect, which is all about how spinning, flying things get driven sideways.

You've seen this in the way spin on a tennis ball can make it do crazy things. But it can be used for a lot of things other than sports, including propelling new kinds of "sailing" ships — or even making weird, rotating cylinder airplanes.

So take a few minutes, enjoy this video (courtesy of the The Kids Should See This) and then consider yourself an expert on the Magnus effect.
