How it works

Prepare a salt-water aquarium and pour in the eggs. Leave the setup in a place with natural light and stable temperature for 1–2 days. The larvae will develop and can be moved to the observation vessel. For a few days feeding is not necessary, and after about 4 weeks they reach maturity. Adult supervision is recommended to ensure proper conditions and handling throughout the experiment.

Not suitable for children under 3 years due to small parts. Intended for ages 8 and up; adult supervision is recommended during the experiment.
