Description
Our popular Water Marbles with a nighttime twist! These marbles start small, but put them in water and they absorb it to grow many times their orginal size! Unlike normal water marbles, however, these will glow in the dark after absorbing light!
Each pack makes about 1/2 liter of Glow-in-dark water marbles. (note that images shows much more than one pack!)
