A long chain of beads can "levitate" Bashny.Net

If you put in a glass chain length of 50 m, consisting of 8000 balls and then throw one end of the chain outside the chain will start by itself "leak" from the tank, forming a bizarre loops and wave - outwardly it resembles the effect of levitation. < br />


This phenomenon has a scientific explanation: the end of the chain, located outside, it begins to rapidly fall down under its own weight, which means that the remaining part of the inside of the chain will also begin to move quickly under the influence of momentum. The part of the chain that remained in the glass, too, must fall down, but in a moment this is not possible, since the fall in such a short period would require an infinite force. Thus, the chain is gradually changing its direction of motion over time, subject to a specific sequence.
