According to the New York Times Science section, "a key to understanding the phenomenon, [said Dr. John Biggins, a Cambridge physicist] is that mathematically, a chain can be thought of as a series of connected rods. When you pick up one end of a rod, two things happen. One end goes up and the other goes down, or tries to. But if the downward force is stopped by the pile of chain beneath there is a kind of kickback, and the rod, or link, is pushed upward. That is what makes the chain rise..."

He continues, "'Finding a new physics problem in an Internet video was,' Dr. Biggins said, 'something of a treat. For a scientist it's "really reassuring" that new problems like this can pop up,' he said."

In other news, physics, (along with Newton's 3rd Law) how do they work?

It really surprises me how few beads can be left in the jar yet the arc and acceleration of the bead string continues to astonish. I think I understand the concepts but then I watch it again and become confused. Wink

I believe this is happening thanks to gravity? I believe weight is also a big factor here.

This is crazy, does it by chance also have something to do with how far the bead falls until this 'chain reaction' starts? No pun intended..
