Looking for a quick way to entertain your child at home? Try this baking soda and vinegar colour experiment! And get set for amazing explosions of colour!
Science Behind the Baking Soda and Vinegar Experiment
What happens when you combine baking soda with vinegar? Fizz! But why does this happen with two seemingly common ingredients. Baking soda is a base and vinegar is an acid. When an acid and a base mix they produce a gas called carbon dioxide.
How to Set Up a Baking Soda and Vinegar Experiment
First off, grab your sensory bin or large tray. I like using a sensory bin because it contains the vinegar that starts to collect makes clean up super easy!
Fill it with a thin layer baking soda. I used an entire box. A box of baking soda is fairly cheap (less than $2) and worth it in my opinion for almost an hour of entertainment!
Next, add several drops of liquid watercolors to several different jars or bowl. If you are using food coloring you will only need a drop or two. Fill the containers 1/3 of the way with water and then fill the rest with vinegar. I added a bit of water to help make the vinegar go a little further. Mix the contents together. Finally, add the eye droppers.
If this is the first time they are using eye droppers they may need to practice this action before hand. Hand them a bowl of water to practice first.
Invite your child to squeeze up the coloured vinegar mixture and then squeeze it out on the baking soda. Watch as it fizzes and explodes with colour!!
This was such a fun activity for my little guy! He loves baking soda and vinegar activities. I swear he could do then everyday! This one did not disappoint!
For these activities I like to use liquid watercolors largely because they are washable but also because they come in a larger container than food colouring. But food coloring will work beautifully with this activity as well!
