Huge Response Before Release! Ranks First in the Rakuten Books Children's Book Category Released today, this book attracted significant attention, particularly from parenting generations, immediately after reservations opened, ranking first in the Rakuten Books Children's Book category (survey period: May 18 to June 14, 2026). This is the highly anticipated second volume following the hit book "Developing Science Skills Through Play: Magical Home Experiment Lab," and is expected to be useful for summer vacation independent research and home study.

Proposed by a Former Elementary School Science Teacher! The Magic of Turning Play Into Learning The author, Mae-mama, is a former elementary school teacher and education professional with science teaching experience. The book was born from the author's belief that "science is not a difficult subject, but something that exists naturally around us and is highly interesting." By weaving scientific wonders into children's favorite activities like play and baking, it fosters scientific thinking and encourages them to ask "Why?" and "How?"

Edible Slime and Gems!? Curiosity Never Stops When It's Delicious The book includes numerous experiments of varying difficulty levels that use common household ingredients such as eggs, gelatin, sugar, store-bought gummies, and marshmallows. After enjoying visually stunning transformations like "Edible Slime," "Catchable Water Droplets," and "Glowing Star Cookies," children can deepen their understanding through explanation pages called "Mae-mama's Delicious Experiment Lab." Since these experiments are edible, children feel a strong sense of achievement and motivation to learn.

Perfect for Summer Vacation Research! Develop the Ability to Think and Organize Independently The book emphasizes a "three magic steps" process (Prediction, Discovery, Reflection) to ensure experiments do not end as simple play. Utilizing the "Experiment Worksheet" downloadable via QR code and the "Shopping Adventure Sheet" for learning calculations of money and quantities helps children develop real-life experience and cognitive skills. This single book makes summer vacation independent projects fun, delicious, and easy to complete.
