Gravity Beads

Watch the video, explanations under the cut again on the video.



If you take a long string with beads and put it in a glass vessel, and then pull out the free end, then ... The beads will fall, but not just fall to the floor, but will be curved in an arc! Scientists at Cambridge University, led by John Biggins, explained why this is happening.

The child can repeat the experience. But here it is more difficult to explain scientifically. Mathematicians considered that the height of the chain above the edge of the vessel is proportional to the square of the speed of the beads. And the higher the vessel is above the ground - the higher will be the arc of the beads soaring into the air.

The effect can definitely find its application at least in the entertainment industry.
