Impossible motion: magnet-like slopes

In this video, wooden balls roll up the slopes just as if they are pulled by a magnet. The behavior of the balls seems impossible, because it is against the gravity. The video is not a computer graphic, but a real scene. What is actually happening is that the orientations of the slopes are perceived oppositely, and hence the descending motion is misinterpreted as ascending motion. This illusion is remarkable in that it is generated by a three-dimensional solid object and physical motion, instead of a two-dimensional picture.

Are you people idiots, or what? Did you even watch the entire video? It's an optical illusion - there are NO magnets! The framework is designed to appear as though it's orientation toward center is uphill - from a single point of view. But as you watch the video, you will see the device is rotated to reveal it's true form and the illusion fails. Please do us all a favor and NEVER vote, mmmm k?

The way to find out what any music is... download free Shazam app... point phone at speaker playing music... and it will tell you what the music is !

This is "Liebe-Ein Unordentliches Gefuhl 4" by Richard David Precht.

Used my Shazam app for that !

Awesome app.

This should be illegal.

Irrefutable proof that humans can only see in two dimensions with a perception of a third.

Very clever use of perspective. Love it. Thumbs up!
