Baking Soda and Vinegar Fireworks

Here’s a fun and safe “Baking Soda and Vinegar Fireworks” activity, great for kids or educational demonstrations. These aren’t actual fireworks with fire or explosions—just a fizzy, foamy eruption that mimics the excitement in a safe and colorful way!

🎆 Baking Soda and Vinegar Fireworks (Foam Eruption)

🧪 Ingredients/Supplies:

• Baking soda (sodium bicarbonate)

• Vinegar (white vinegar works best)

• Food coloring (optional, for a “firework” effect)

• Dish soap (optional, makes it foamier)

• Small clear cups or containers

• A tray or large shallow container (to contain the mess)

• Spoon or popsicle stick

🧁 Instructions:

1. Set Up the Cups:

   • Place small clear cups or containers on a tray or in a shallow bin to catch overflow.

2. Add Baking Soda:

   • Put 2–3 tablespoons of baking soda into each cup.

3. Add Food Coloring (Optional):

   • Drop 1–2 drops of different food coloring into each cup for a colorful eruption.

   • Don’t mix it—let it sit on top for a fun, surprise effect.

4. Add Dish Soap (Optional):

   • Add a small squirt (½ teaspoon) of dish soap to each cup for a foamy, longer-lasting eruption.

5. Pour the Vinegar:

   • Quickly pour about ¼ cup of vinegar into the cup and watch the fizzy “fireworks” rise and spill over!

🌈 Fireworks Tips:

• Use different food colorings in different cups for a rainbow effect.

• Layer baking soda and food coloring in a tall clear glass for a “firework fountain” look.

• You can make this more explosive by using more vinegar or a narrow-necked bottle for a higher eruption.

⚠️ Safety Notes:

• This activity is safe and non-toxic, but supervise young children.

• It can be messy, so do it outside or on a washable surface.
