The growing unicorn egg from Gimmicks provides a fascinating observation experience in the children's room. Simply place the colourful, 11 cm rainbow egg in a container of water. Within 12 to 24 hours, the shell breaks open and a small toy unicorn emerges, which continues to grow in the water. Which of the various, brightly coloured unicorns is hidden inside the egg remains an exciting surprise until it hatches. This magical experiment is ideal as a small gift, souvenir or as a playful introduction to simple biological processes.
