The best optical illusion of the year
2010/05/18 Aulestiarte Lete, Izaro - Elhuyar Zientziaren Komunikazioa
Ilcluon of the Year Contest has awarded this unique video in its sixth edition. Founded by Japanese mathematician Koukichi Sugghara, the video seems to challenge the law of gravity.
As attracted by a magnet, in the video you can see how some wooden balls climb up the ramp. It seems impossible, but it is an optical illusion. Thanks to the strategic orientations of the ramps, it seems to the viewer that the downward movement that is normal is ascending.
