Cut 'em open and pour them in a jar with a tight seal. When you need a pack, microwave hell out of some and rubber band them into a piece of coffee filter.

The colored beads indicate how water saturated they are. When they're nuked and dried out, they change color. YMMV as some manufacturers use different colors or none at all. Whatever. Nuke 'em and reuse.

It's an exciting hobby.

Be careful that you don’t mix in any of the oxygen absorbing packs. Those ones contain iron, which I unfortunately learned after my dog ate one. I haven’t tried microwaving them but I’m guessing that the iron filings would get pretty spicy in there.
