Baking-Soda Balloon
Professor O will help you learn: Vinegar and baking soda make carbon dioxide gas, which fills the balloon on its own.
⚠️ Balloons are a choking risk for children under 3 — keep them well away and bin any burst pieces. The fizzing can splutter, so keep the mixture away from eyes.
Play through the project step by step, with narration read aloud.

Bottle-Top Volcano
A chemical reaction: an acid (vinegar) and a base (baking soda) make carbon dioxide gas, which is the fizzy foam.
Mummified Apple Experiment
Children test how the ancient Egyptians preserved mummies by burying apple slices in salt and bicarbonate of soda for a week. The salts draw water out of the apple, and without water the things that cause rot cannot grow. It is a real fair test with measuring and recording.
