Boy oh boy did the kids love this fun color explosion activity! And I love any activity that is educational and manages to keep my kids totally focused and engaged for as long as this one did! This is a great preschool science activity that also doubles as an opportunity teach colors.
Note: For more science activities, see my Science Activities for Kids page.
I set up this activity by pouring baking soda on to a little painting palette for each kid. I then put the painting palette on a craft tray in order to contain the mess. I added a few plastic pipettes as well.
In the cups of a muffin tin I put a few drops of liquid water color and then filled the rest with vinegar.
Then I showed the kids how to suck the liquid into their pipettes and drip it onto their baking soda.
Amazement ensued as they watched the liquid explode into a frothy, colorful mess.
The kids experimented with different colors and with mixing colors.
They had so much fun, they asked to do it again – twice!
