RE: Question about "blue spring"

Is this in reference to the blue mechanical spring found in fischertechnik?

Compress the spring into a piece of pipe or tubing that is the right length. Hold the spring inside with a hinge that closes the end of the tube. Release the hinge and the spring will "jump up".
