Hi Chris.

Thanks for the link. The anecdotal information it contains may inspire some teams to go do a little research about the material properties of elastomers used for storing potential energy for kicking, and that would be a good thing (learning!). Maybe a team or two will even run some simple quantitative experiments and post the results - like hanging a 10 pound weight on the end of a piece of surgical tubing and measuring its stretched length at room temperature, then taking it outdoors in the freezing cold and repeating the measurement. Then do the same with a "bungee cord".

As for the relative temperature-behavior merits of bungee cords vs surgical (latex) tubing, which is what we were discussing, I doubt that even a 20 degree change in room temperature would make "surgical tubing" change its behavior noticeably more than a "bungee cord"... especially if it's a bungee cord made with latex rubber!
