I found this creative idea on Mom to 2 Posh Lil Divas, an idea that can be very useful for a party. Is very easy, all you need is baking soda, vinegar, plastic bottle, balloon and a funnel. What to do: use a funnel to pour vinegar into your bottle (need to fill about 1/3 of the bottle). Pour baking soda into your balloon (fill the balloon approx. 1/2 way). Cover the top of the bottle and lift your balloon and let the baking soda fall into the vinegar. Enjoy!

*** Carbon Dioxide gas will inflate the balloons but they do not “fly” like helium inflated balloons as it is not the same kind of gas. *** This project can be useful for kids, to fill balloons also you can buy a small helium tank. This is more for a science project. ***
