OK, I'll try a serious answer.
You need a serious lever and a big weight.

The {} is the spring, the ***** is the weight and ## the floor.
You need to measure the spring displacement from free length.
Of course, since the spring rate might be anywhere b/n 270 and 510 lbs/in
you'll need a 5' lever and 25lbs to get a reasonable relative error.
You can also use the number of winds, the spring gauge, and the free length
to calculate the theoretical spring rate, but I don't have the formula handy
and I'm too lazy to work it out.
