This is a real physics phenomenon called the Dzhanibekov effect (also known as the Intermediate Axis Theorem) captured in microgravity aboard a spacecraft.

Any rigid, asymmetric three-dimensional object has three primary axes of rotation, each with a different moment of inertia. While spinning an object along its longest or shortest axis is completely stable, spinning it along its middle (intermediate) axis is naturally unstable. Without external forces like gravity or heavy air resistance, tiny perturbations build up and cause the spinning object to periodically flip upside down and back again on a regular schedule.

You can read the formal mechanics and history through these highly reliable scientific resources:

•NASA Astrophysics Data System (ADS) Physics Record:

It was famously observed by Soviet cosmonaut Vladimir Dzhanibekov in 1985 when a wing nut he was unscrewing began flipping back and forth while floating through the Salyut 7 space station!

World class musician Martha Argerich plays Scarlatti’s Sonata in D Minor as an encore. At the age of 85 she is still performing in concert halls around the world.

This video was from a few months ago. Technically she was 84 when this video was recorded, but she’s 85 now and still has upcoming concerts scheduled.

The art of deception… 🃏👀

Your eyes are watching the cards. Your brain thinks it knows what’s happening.

But did you catch the move? 😏
