Buy several individual cans of drink such as Capri Sun and
put in your home freezer for at least a day prior to leaving
on your camping trip. They make excellent substitutes for
the messy ice cubes that melt in cool box or those freeze
packs.
They are convenient, take up less room because as they melt
inside their containers you still have a cold drink and your
food stays cool at the same time. A light weight alternative
Another similar tip is to fill a large plastic container
with water and freeze until solid. As it melts, this can then
provide fresh cold water gradually over a long period of time.
