Magical Hands-Free Inflating Balloons

Make a balloon inflater with common materials found at home! A perfect project that counts as a science experiment and a fun activity.

Step-by-step tutorial

  • Step 1

    Add 4 TBSP of vinegar to the bottle. To make it more kid-doable, we measured the vinegar into the measuring cup, then H poured the vinegar through the funnel into the bottle himself.

    Why it works: When baking soda and vinegar come into contact, they form carbon dioxide. This gas fills the bottle and can't escape, so it rushes into the balloon, causing it to inflate.
