Ingredients
  

Materials

  • 1 bottle Plastic bottle (empty and clean, preferably 16 oz)
  • 2 tablespoons Baking soda Approximately
  • 1 cup Vinegar Approximately
  • 1 funnel Funnel Optional, for easier pouring
  • various balloons Balloons (various colors)
  • as needed drops Food coloring Optional for a colorful effect
  • as needed spoons Measuring cups and spoons For accurate measurements

Instructions
 

Preparation

  • Stretch the balloon a little bit to make it easier to inflate later.
  • Use the funnel to carefully pour baking soda into the balloon until it’s about 1/3 full.
  • Pour the vinegar into the plastic bottle. If you want a colorful effect, add a few drops of food coloring to the vinegar.

Setup

  • Carefully stretch the neck of the balloon over the opening of the bottle, ensuring none of the baking soda spills into the vinegar just yet.

Execute the Experiment

  • Lift the balloon, allowing the baking soda to fall into the vinegar.
  • Step back and watch the reaction unfold!

Observation

  • Watch the vinegar react with the baking soda, creating bubbles of carbon dioxide gas that inflate the balloon.
  • Listen to the fizzing sound and watch the balloon grow.

Notes

For a sparkly effect, add a pinch of glitter to the balloon. Try using larger or smaller balloons to see how the reaction differs. Store any unused baking soda and vinegar in airtight containers.
