Fizzy science
Add some simple fizzy fun to your day with this classic kitchen science experiment.
This satisfying little science activity is a hit with toddlers and big kids alike. Just set out a tray with baking soda and let your child add vinegar using a dropper, spoon, or squeezy bottle. The chemical reaction creates an exciting fizzing sound and bubbling effect - perfect for curious hands and minds.
You can easily theme it up with colours (rainbows, colour mixing, potions) or add kitchen tools for scooping, stirring and pouring. It’s great for building fine motor skills, exploring...
