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.

I can't say I've ever used a microwave, but I usually bake or convection bake the beads at just above the boiling point of water (something like 225-240 degrees) for an hour or two in the oven.

I'd be concerned with the microwave that they might get too hot myself.
