Many moons ago....in medic class, our instructors had a mantra about checking out the IV fluid.....something about:Right solution, check expiration date, bag intact, nothing swimming in it.....

One day while going through a megacode, I had to hang a bag....being the wiseguy, I went through the 'routine' of checking the bag.....when I came to the 'nothing swimming in it' part, I stopped and told them that I couldn't use this bag as "Something was swimming in it." I had cut open the bag and put a plastic fish inside....Aside from the laughs, I did get a few orders for the bags.....

All I needed was a "Seal A Meal" bag sealer.....While it won't allow for repeated opening and closing, it will allow you to seal something indside it....If you take an expired bag that has not been used (still sealed) and cut the top, when you seal it, it will still be 'sealed' shut. You know how durable they are so it will provide a lot of protection for whatever is in it.
