Copyright Instruction 1 Pour bicarb soda into container, carefully mix in a few drops of food colouring at a time with a spoon until you get the desired colour. The mixture should be crumbly, and holds its shape when pressed with the spoon. If not, add a few drops of water and mix, repeat until it does. 2 Fill the muffin tray or ice cube tray with the mixture, about 2/3 of the way up. Pack down with the back of the spoon. 3 Leave to dry for an hour then turn out onto a plate. 4 Drip vinegar on top of the fizzy bomb or chuck one into a cup of vinegar! 5 School science visits since 2004! – Curriculum-linked & award-winning incursions. – Over 40 primary & high school programs to choose from. – Designed by experienced educators. – Over 2 million students reached. – Face to face incursions & online programs available. – Early learning centre visits too! 6 Online courses for teachers & parents – Help students learn how science really works 7 Want to dive into acid-base chemistry? Get the 30-minute video + PDF + curriculum links for your class here! What is the chemical reaction occurring here? Vinegar + Bicarbonate Soda —> Carbonic Acid + Sodium Acetate The carbonic acid is unstable though, so it breaks down into water and carbon dioxide forming the bubbles you see when the bicarb soda comes in contact with vinegar. More vinegar and bicarbonate soda experiments here Variables to test More on variables here Add bath crystals vs no bath crystals. Is the chemical reaction the same speed? Is baking soda the same as bicarbonate soda? Remove the food colouring from the recipe. Does the food colouring make any difference? Learn more!
