Icepacks. As the summer season approaches, it is the perfect time of the year for this. Rather than buy commercial icepacks, dishsoap bottles can be filled with water and frozen. Because of their small size they can fit into the smaller chests, or you can use many to fill up a larger chest. You could use other bottles, but dishsoap caps make it easier to squeeze the air out, allowing room for the water to expand as it freezes. I have about 8 in the deep-freeze right now! Bonus: they will probably help keep my food cold in the event of a power failure.
Replacement glue bottles: I’ve gone through quite a few bottles of wood glue building my projects. Some have worked better than others, but they always get clogged. It might have something to do with the long necks, or maybe I should just close them properly when done. Once clogged, they are impossible to clean. I had a glue bottle that was so damaged I threw out the cap, covered it with plastic wrap, and had to use a stick to apply the glue. One of my children suggested that I use a dish soap bottle. It worked perfectly. The bottle was easy to open and close, spreads the glue easilly, and doesn’t clog. I made a quick paper label so no one uses it as dish soap. Now I can buy my wood glue in large, bulk containers and save money too.
