Olympia and her daughter Viola explore how bicarbonate of soda reacts with different liquids from around the house. Some fizz vigorously, others bubble gently, and some substances don’t appear to react at all. These simple chemical reactions introduce the idea that substances can react together to make a new substance, and are an excellent starting point for looking closely at the world around us. This experiment can be a little messy, but that's part of the fun.

When bicarbonate of soda reacts with substances like vinegar, carbon dioxide is given off as a gas, which forms the bubbles you see as the reaction fizzes. Experimenting with different liquids shows how some have certain things in common with each other. Acidic liquids cause fizzing while some don’t react. After exploring the different liquids, Olympia and Viola use this fizzing reaction to make a balloon inflate itself with carbon dioxide on top of a bottle.

This series of ExpeRimental is supported by the Royal Society of Chemistry.

This is the first of three special ExpeRimental films released in British Science Week.

ExpeRimental, brought to you by the Royal Institution of Great Britain, is a series of free short films that make it fun, easy and cheap to do science at home with children aged 4 to 10. Our films give you lots of ideas for kids' activities that will help you explore the world around you, question and experiment together. We'll show you how to do the activity and how to make sure adults and children get the most out of it.
