Pour baking soda into several containers (¼ cup in each).
Add 5-7 drops of food coloring to the containers (a different color in each one), and ask your tinybean to gentle stir the baking soda until the color is distributed a bit. Don’t worry about blending it perfectly!
Now fill up a dropper or a spoon with white vinegar and let your kiddo pour it into each cup or bowl.
Woosh! Carbon dioxide is created, making lots of fun fizzy bubbles.
(Pssst – you’ll want a big box of baking soda to accommodate requests of “AGAIN, AGAIN!”)
