"That's incredible!" Watch a basketball fly thanks to cool Magnus effect experiment

TASMANIA, AUSTRALIA -- A group of guys grabbed a basketball to test out a pretty neat 'Magnus effect' experiment.

In a YouTube video, the men stand at the top of the 415 foot tall Gordon Dam in Tasmania, Australia and drop a basketball over the edge. The ball sways a little but ultimately stays in a downward path.

Next, they drop another basketball with a bit of a backspin on the ball -- and the result is 'incredible.'
