My kids love doing crafts, and experiments. One of their favourites and mine also is fizzing colours. Not only is this a cheap experiment to do it also helps kids learn colours and learn about mixing their colours.

playYour ingredient list is simple:

1. Baking soda

2. White vinegar

3. Food colouring

Your Supply List is

1. Pan

2. Plastic eye droppers or syringe

3. Containers for colours

mixI used a 9×13 baking dish and short mason jars for our experiment. They are all dishwasher safe so it makes for easy clean up. The plastic eye droppers are awesome, but if you cannot find them a simple medicine syringe works as well.

So the instructions are simple: pour baking soda in a pan. Pour vinegar in as many dishes as you have food colouring. Put a few drops of food colouring in each vinegar dish. Now let your child go wild.

We started out with pretty colours all over our dish. And then we started seeing how each colour would mix with others.



By the end we had a lot of pretty colours, and a big pool of brown. Payson had so much fun seeing the reaction between the vinegar and the baking soda, and we talked a lot about colours and how they mix to make new ones.

And the best part about this experiment and nice weather?? All I had to do was fill a cup with water and rinse of their picnic table!! I rinsed out the baking soda in the sink and put all the dishes in the dishwasher. And that was that. This is also a great rainy day activity for inside.
