I know its not that time of year but the other day I was in the pool
supply store getting some supplies for thre hot tub, and they had a
big display of a silver blue translucent bubble wrap looing material.


We used to have a similar blue bubble wrap type pool cover on our pool. It
looked something like this:

One winter we had a few chilly nights, which is abnormal for this part of
California. The water on the top of the pool cover froze and made tons of
plastic floating flecks, because many of the bubbles broke and separated
from the pool cover. Not sure if it was because the pool cover was old and
the frost just finished the job of that's normal when water freezes on it.
