- The stones glow as a result of photoluminescence， so kids get a science lesson by interacting with them. Recommended for children ages 6 and up. The pebbles measure 1” in diameter. May present a choking hazard for younger children
- The stones glow best when fully charged， after at least 2 hours in sun or bright indoor light. The brightest glow lasts about 1.5 hours and then fades over time. Stones continue to glow slightly for up to 12 hours.
