Over the coarse of a few projects, you can accumulate quite a collection of small screws, nails, and other small parts. There are several ways you can store these items; baby food jars, small paper bags, soup cans, or even a multi-drawer small parts organizer. The trick is to be able to quickly see what is inside each container without having to waste time searching. Using your hot glue gun, attach a sample of the small piece on the outside of the container. This will give you a quick, visual reminder of what's inside.
Be sure the thermostat is set in the cooling mode. Just setting the dial below room temperature will not activate the air conditioning if it is set in the heat mode.
