You have put it in wrong order!! 😀First see Slinky DropThen see Slinky AnswerThen see Slinky Extended,By the way nice find!The example of bat-ball swing was kind of wrong though. That one works on principle's of momentum transfer m1v1 = m2v2This one worked on tension v/s gravity.Information transfer theory (ball doesnt know that top has been released! 😀) that he put is kind of vague, but yes its easy for general understanding.
