Magically growing crystals on the back of the dinosaurs are so fascinating for kids! With Alex Toys Grow Crystal Dino Fun Science Kit children can actually see the crystals grow in minutes! The crystal dino kit includes precut and colored paper dinosaur figure, palm tree and shrub, 2 plastic trays, magic crystal liquid (.7 fl oz.). Follow the easy instructions to place the dinosaur and palm tree cutouts in the trays and add the crystal liquid. The colorful magic garden of crystals will grow on the paper figures right in front of your eyes. Educational Toys Planet recommends to place the trays where you want to keep them for days, and not to move them during crystal growing due to the fragile nature of the magic crystals. The magic crystals fully bloom in a few hours and can last for up to a few weeks. Grow Crystal Dino Fun Science Kit is a great science toy gift for children.
