Recycling for "fridge" use

I don't know if anyone has access to "pap saks" (foil bags) like we do in South Africa.  Here one can buy anything from bulk tomato sauce, fruit juice, wine, etc in this packaging.

I have a friend who uses these bags for cooking in.  Removing the tap, she cuts open a corner, turns it inside out, removes the plastic lining, turns it round the right way again, and then she gives it a good clean.  She fills it with vegetables, herbs and a dash of white wine.  She then seals the bag by folding it over and fastening it with a paper-clip, pours a bit of water in the bottom of a "potjie" pot, pops in the foil bag, places the lid on and cooks it over a fire.

However, I have found, what I reckon, is a pretty cool way of assisting our food preservation on the farm.  I will be using them as a giant ice blocks.

First, finish the contents of the bag - an enjoyable experience regardless of what it contained :)

Then, open the tap and rinse out the bag well... (tedious work, but I reckon it's worth it)...

Rinse out the bag, and fill with water

...after rinsing well, fill three quarters of the bag with water, and squash the bag to remove most of the air.  (Allow for some expansion space, otherwise the bag will burst in the freezer.)  Close the tap.

Squash the bag to remove most of the air

Place the water-filled bag in the freezer.  When it is frozen, it can be used for keeping food in cooler boxes cool, as an ice remedy for an injury, or as a cooling method for buckets filled with water.

Pop in the freezer until frozen

As it is less bulky than a 5lt bottle, this is exactly how I am going to create a fridge in my cooler box on the farm!

And, Jane, I thought that perhaps, next summer, you could use it in the top of your beautiful old ice box...?  It doesn't drip LOL
