Ingredients Method Notes

Ingredients
  

  • 1 cup granulated sugar
  • 1–2 tablespoons baking soda
  • 1/2 cup white vinegar
  • food coloring any colors you like
  • glitter optional, for extra sparkle

Method
 

  1. Place the sugar in a shallow dish or tray and mix in the baking soda.
  2. Spread the mixture evenly across the dish to create the experiment base.
  3. Add drops of food coloring in different spots across the sugar mixture.
  4. Slowly pour or drop the vinegar onto the mixture using a spoon or dropper.
  5. Watch as the mixture begins to fizz, bubble, and create colorful bursts that look like tiny fireworks.

Notes

This experiment works because of a chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate). When they combine, they produce carbon dioxide gas, which creates the bubbling and fizzing effect. Adding food coloring makes the reaction look like colorful fireworks. For best results, perform the experiment in a tray to catch the bubbles and avoid spills.
