solar shower bag
heat test
We bought two of
the solar shower bags you fill with water & place in the sun to warm
the water. We noticed on one bag it said to fill with water & place
the clear side up while the other said to place the black up.
An experimented
was needed. We filled both with water, removing as much air as
possible & then placed them as per the instructions. After a couple
of hours, the one placed clear side up was warm, while the one
placed black side up was still cool.
We then decided
to turned the clear side up instead and after an hour this bag was
warm enough to use for a shower.
