Step by step |
|
1) Pour the white vinegar into 3 plastic containers evenly - about 1/2 way. 2) Drip a few drops of different food colouring into each plastic container. 3) Pour a spoonful of baking soda into each plastic container to watch it fizz! If you would like to see the rainbow colours fizzle at the same time, you would have to pour the baking soda into each container at a fast speed. 4) Don't take your eyes off the containers! It will start to fizz and bubble, before rising and overflowing onto your table. The reaction happens quickly. 5) Remove the containers and watch the colours mix and melt together on your table surface/paper. Share what new colours you can see! 6) If you have remaining solution in the containers, use the dropper to mix the coloured liquids around to see what new colours you can create!

Why does the colourful vinegar fizz, bubble and rise?
Vinegar is an acid, while baking soda is a base! When they are mixed together, it creates a gas called Carbon Dioxide. That creates the fizz and bubbles, while causing it to rise!
