Ingredients
  

  • 1/2 cup baking soda
  • 1/4 cup dish soap
  • Red food coloring
  • Blue food coloring
  • 1 cup vinegar
  • Water (optional) just a splash if you want a slightly different consistency
  • Glitter (optional)
  • Non-metallic patriotic confetti (optional)

Equipment

  • Large tray, bin, or plastic tub
  • Spoon or hands
  • Bowl (optional for prep)
  • Small plastic toys or scoops (optional)
  • Star-shaped sponges (optional)

Method
 

  1. First things first, lay down your large tray, bin, or plastic tub on a flat, easy-to-clean surface. This is going to contain all the bubbly goodness.
  2. Now, pour your 1/2 cup of baking soda right into the center of the bin.
  3. Next, add the 1/4 cup of dish soap over the baking soda. It might look a little clumpy, and that’s totally okay!
  4. Time for some color! Gently add a few drops of red food coloring in various spots all over the baking soda and soap mixture. Think of it like painting little fireworks.
  5. In different areas, add a few drops of blue food coloring. You want to create distinct patches of color.
  6. Now, very gently, use a spoon or your hands to swirl the colors together a bit. The key here is to not overmix; you want to keep some of those color separations so the "firecracker" effect is more pronounced when the fizzing starts. If you’re adding glitter or confetti, now’s the time to sprinkle it in!
  7. Feeling like the foam could be a little looser or softer? You can add a small splash of water and gently mix it in. This is totally optional and depends on the texture you’re going for.
  8. And now for the grand finale! Slowly and carefully pour the 1 cup of vinegar over the colorful mixture. Watch in amazement as it starts to foam up and fizz, creating your very own "firecracker" eruption!
  9. Get ready to explore! Let your little ones (or yourself!) dive in. Scoop, squish, and swirl the foam. If you’re using star-shaped sponges or scoop tools, now’s the perfect time to add them for even more tactile fun. It's such a satisfying sensory experience, almost as delightful as creating these delicious easy homemade peanut butter balls!

Notes

Protect your surfaces: While the ingredients are safe, food coloring can stain. Using a large tray or doing this activity outside is a great idea! You can adjust the amount of vinegar slightly. More vinegar might create a more vigorous fizz, but start with the recommended amount. Always supervise young children during this activity, especially when food coloring and vinegar are involved. You can pre-measure the baking soda and dish soap into a bowl and have the food coloring ready to go. Then, when it’s time for fun, you just need to add the colors and vinegar!
