Equipment

  • Small Plastic Bottle
  • Funnel or Paper Cone

Ingredients
  

Required Supplies

  • 1 Balloon any standard party balloon
  • 1 Small Plastic Bottle clean, empty water bottle is perfect
  • 2 tbsp Baking Soda (or 3 tbsp)
  • 1/2 cup Vinegar plain white vinegar is ideal
  • Funnel or Paper Cone for mess-free transfer

Optional Additions

  • Food Coloring optional addition to vinegar
  • Glitter optional addition to vinegar
  • Essential Oils optional addition to vinegar

Instructions
 

  • Step 1: Grab your balloon and funnel (or paper cone). Insert the funnel tip into the balloon opening. Measure out 2-3 tablespoons of baking soda and gently pour it through the funnel into the balloon. Set the balloon aside carefully.
  • Step 2: Take your clean plastic bottle. Measure out ½ cup of vinegar and pour it into the bottle. Add any optional additions like food coloring, glitter, or essential oil to the vinegar. Give it a little swirl.
  • Step 3: Carefully stretch the neck of the balloon over the opening of the bottle. Be extra careful NOT to let the baking soda fall into the vinegar yet. Keep the balloon hanging loosely down the side of the bottle. Make sure the seal is tight around the bottle opening.
  • Step 4: Lift the balloon upright so the baking soda inside tumbles down into the bottle and meets the vinegar. Observe closely as the mixture fizzes and bubbles, and the balloon starts to inflate!

Notes

Make sure your baking soda and vinegar are fresh for a vigorous reaction. Secure the balloon tightly over the bottle opening to prevent gas escaping. Don't overfill the bottle with vinegar. Always have adult supervision. Do the experiment on a tray for easy cleanup as reactions can get bubbly.
