Here are the tips you
need to pack your groceries during your next grocery store visit...
Cold Stuff In the Center ~
Start by putting the cold stuff in the middle of the cooler bag.
This will not only insulate the cold items from getting warm, but it will keep
cool the cans wrapped around the outside.
Cans On The Bottom ~
Next line up your cans in a ring around the outer edges of your cooler.
Lots of people make the mistake of tossing the drinks in last, but cold sinks,
while heat rises. So drinks sitting on top will never get as frosty cold up
there as they will on the bottom.
Warm Stuff On The Top ~
Remembering that heat rises, putting the warm stuff on top is the last essential
part of packing your grocery cooler bag.
