And as long as I being serious (and temporarily sober), I'd just like to point out that temperatures in the range that people can normally deal with, don't affect darts. To get any significant expansion of polyurethane foam, you have to exceed 180° fahrenheit. In some formulations over 200°.

Likewise there is no evidence that polyurethane foam shrinks significantly in the cold. Again, unless you're talking liquid Nitrogen cold, then that's another matter. But at sub-zero temperatures polyurethane foam does not shrink significantly.

You can prove it yourself. Stick a bunch of darts in the freezer over night, then compare them to room temperature darts. Guarantee, you won't find any significant difference in diameter or length. Why don't you try making stefan darts?
