Just dampen paper towel, use the paper towel to add moisture to the beads. REMEMBER, Use only DISTILLED water. The beads should be clear when they have absorbed the proper amount of moisture. They should NOT be soaked or soaking wet at any time during this process. If using a "spritzing" bottle, make sure to rinse well with DISTILLED water before spraying the beads. The beads will give up moisture to maintain the humidity. When the amount of "cloudy" beads out number the "Clear" beads, it's time to add more moisture to them. DISTILLED water only.
