    The inner spring broke earlier in the video, you can see small metal chips flying out from inside the spring. This left the outer spring alone with a damaged internal spring to interfere with the outer springs flex. See the chip at .33 seconds.

    Valvesprings are the most overlooked component in engines.

      It's a valve spring that closes a valve in an internal combustion engine. Even at mild RPM's (1400) they need to open and close over ten times a second. You can buy racing motorcycles now that can reach well beyond 10.000 RPM's and there have been vehicles (old Honda CBR250rr) that could achieve 19.000 (nineteen-thousand) revolutions per minute where this valve would be opening and closing over one hundred and fifty times every second.
      So to sum that all up: "Spring."

      @@stalincat2457 No idea how you did the math - being 2yrs later you probs don't remember either - but your numbers here are off by more than a factor of 2.
      19,000 RPM means the valve (and every component in combustion cycle) is completing over 300 repetitions per second. 316 + change, in fact.
      EDIT: Nevermind, I just realised you were right. Four stroke engine means each intake/exhaust valve is opening/closing one time for every two revolutions of the crankshaft - the factor of 2 I blonded out on before.

    These spring videos are so pointless... please show us a video of a normal spring that doesn't bounce?? Cause as far as I am concerned thts what spring does
