Check out the pendulum of lights that can create amazing visual effects [video]

You may have seen countless pendulums in motion, right? But, after watching the video above, posted by BRUSSPUP on YouTube, would you explain why the balls that appear hanging do not all move at the same time or in the same way?

In fact, the different trajectories of the balls occur because each one of them is hung with a different length of string. Thus, when all the pendulums begin to move at the same time, each one takes a trajectory, returning to the starting position after approximately one minute.

Check below another video involving the pendulum of lights, but now showing how the trick works and in the dark!
