Thanks To The Magnus Effect, This Basketball Does Something Pretty Weird When Dropped
Drop a basketball from a height, you've got a few flights of stairs to descend to retrieve it and you might even owe an apology to an angry passer-by. But if you give it enough height and add a dash of backspin, you can watch it say GOODBYE, FRIEND as it curves a great distance away from its intended flight path. This is the Magnus effect, where the descending, spinning basketball drags air around it, forming areas of lower pressure and high pressure, causing it to swerve away.

Listen to the instrument da Vinci invented but never got to hear It's startling to think of the multitude of objects Leonardo da Vinci conceptualized, and it's a tad heartbreaking to realize he saw so few of them actualized. But nearly 500 years after da Vinci sketched his plans for a musical instrument he dubbed the Viola Organista, Polish concert pianist Slawomir Zubrzycki spent more than 5,000 hours making da Vinci's idea a reality.
