Magic Water Marbles - Multicolor

115 grams of marbles in assorted colors: our magic marbles grow right before your eyes—just add water! Simply place the dehydrated marbles in a large tub…fill the tub with water…and watch the marbles become bigger & bigger. The more water you add, the bigger they grow! Then invite children to reach their hands into the marbles—for a unique sensory experience they won’t be able to resist. Best of all, the marbles can be used again & again—simply dry them out to return them to their original size! Sensory tubs sold separately.
