A little messy
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.
Then slip the end of the balloon over the end of your funnel and measure 1 TBSP of baking soda into the funnel.
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.
