Another Fun Experiment

The Deer Park After School Program was at it again with another science experiment! This time we explored gas with balloons. In this activity we blew up balloons without using our mouths! Instead we used vinegar and baking soda! 

When we used the baking soda and the vinegar it created an acid-base reaction. When combined/mixed they create a gas – carbon dioxide. Gasses need room to spread, so the carbon dioxide fills the bottle and then moves into the balloon inflating it! Want to make this experiment at home? Here’s how… 

What You Need:

  • baking soda
  • vinegar
  • plastic bottle(s)
  • balloon
  • funnels (we used 2)

 

What To Do:

  1. Using your funnel pour vinegar into your bottle. You only need to fill about 1/3 of the bottle

2.  Using another (dry) funnel pour baking soda into your balloon. Fill the balloon approx. 1/2 way.

 3.  Cover the top of the bottle with you balloon.

*Make sure you don’t let the baking soda spill into the bottle prematurely.*

4. When ready, lift your balloon and let the baking soda fall into the vinegar.

5. Watch as the mixture fizzes, bubbles & expands your balloon!
