Today I came across fizzy hearts over at B-Inspired Mama and thought it would be a good way to occupy a cranky preschooler. We love playing with baking soda and vinegar so I knew it would be a hit. It only took a few minutes to set up and the mess wasn't too bad.
Of course we eventually had to add the vinegar to the baking dish and turn it into sensory fun. We both have pink hands! For a half hour I got smiles and giggles. She wants to do it again tomorrow.
