🧪 Real science, kitchen-sized

36 of the 51 experiments need nothing but everyday kitchen and household items, not even a candle or a match. Most use things like baking soda, vinegar, food coloring, balloons, cups and jars, and every experiment lists exactly what you need. When you experiment together, it’s quality FUN time for both of you.

📱 No printer needed

Read every story and experiment on a tablet, phone or computer, and print only the pages you love. The pages are A4. On US Letter paper, choose “Fit to page” in your print settings.

🍎 For teachers

Made for preschool, kindergarten and early elementary groups too. Read the story at circle time, let the children vote on what will happen, then do the experiment together. Every adventure says what children will learn.

👩‍🔬 Made by a physicist
