Baking Soda + (Vinegar + Food Coloring) = Toddler Awesomeness
Use a medicine dropper. My kid could do this for hours. When the actual experiment turns to mush he prefers combining the rest of the food coloring and vinegar solution to make new colors. Then we start all over again. He gets focused, the house gets quiet for a few minutes, I get a break while knowing he’s getting something out of this, which makes me happy! Enjoy!
I think this is just too cool. and would be a great way to show how colors mix, as well as, to show science.
