Professor O will help you learn: Whisking egg whites traps thousands of tiny air bubbles, and sugar holds them in place so the foam stands in ghostly peaks. Slow baking dries the foam into a crisp shell. Children see a liquid turn into a foam and then a solid.
⚠️ Contains egg. An adult should separate the eggs, use the electric whisk and handle the oven. Do not eat raw mixture. Check chocolate or icing decorations for allergens such as milk and soya.
Play through the project step by step, with narration read aloud.

Make it your own: Whisk one egg white in a slightly greasy bowl and one in a clean bowl, and compare how well each foams to find out why bakers keep bowls spotless.
