Why do colored freezy pops turn clear when left outside in the cold?

  1. Aug 30, 2011 #1
    So this last winter, my roommates and I left a bunch of freezy pops outside to get cold fast (the temp was -20F). They were in clear plastic and may have been exposed to the sun.

    After about a day, we went to pick them up, and they had all turned clear. They stayed clear even when brought to warmer temps. Why might this be?

    No idea. My freezy pops stay colored even when frozen. But I don't freeze mine to -20 either.

    Why is it that a thread called "what is time?" got hundreds of replies, when my legitimate scientific inquiry gets one? :cry:
