Grow A Horse

Gallop into a fun-filled science experiment with the Master Toys Grow A Horse novelty toy! Perfect for little equestrians and curious kids alike, this pocket-sized pony packs a massive surprise. Simply submerge the horse figurine in a jar of water and watch it magically expand up to 600% of its original size over 2 to 3 days. It is a fantastic, hands-on way to teach kids patience and observation. Once the horse is fully grown, take it out of the water to let it dry out, shrink back down, and start the magical growth process all over again.
