Toy growing-in-water unicorn egg 6 cm by LEANToys, 4 colors

LEANToys growing-in-water unicorn egg is a compact novelty toy that visibly expands when placed in water. The product begins as a textured egg about 6 cm in size and, as the outer shell softens and dissolves, a small soft unicorn figure emerges and increases in size. Available in four colors, the toy is designed for simple, supervised play and for demonstrating basic principles of absorption and material expansion.

Advantages

The toy provides a clear visual change as the egg absorbs water and the unicorn grows, making it useful for sensory engagement and short educational experiments. Its initial compact size and lightweight construction make it easy to store and hand out as party favors. The soft final figure is suitable for tactile play, and the four-color option lets buyers choose or collect different variants.

Suitable for

• Sensory play and tactile exploration for children
• Bath time entertainment and water-based activities
• Party favors, small gifts, and surprise toys
• Simple classroom demonstrations of absorption and material expansion

Key specifications

• Initial size: approximately 6 cm in egg form
• Final form: small soft unicorn figure after water expansion
• Colour options: four different colours available
• Material behaviour: designed to absorb water and expand as outer shell dissolves
• Intended use: indoor water-based play under supervision

How to use

Place the 6 cm egg in a container of room-temperature water and leave it submerged. Over time, the egg will absorb water, the outer shell will soften, and the unicorn figure will gradually expand and emerge. Monitor the process periodically; the time required for full expansion depends on water temperature and container size. Once expansion is complete, remove excess shell residue and allow the soft figure to be handled or displayed.

Usage recommendations

Use under adult supervision, especially with young children. Do not ingest the toy or any dissolved shell pieces. Replace the water and clean the container after the demonstration. Keep away from very young children and pets who might attempt to swallow small fragments.
