How to Blow Up a Balloon...

Here is yet another carbon dioxide experiment that was just a blast.  We poured baking soda into balloons using funnels.  If you blow up the balloon first, then let the air out, it makes the baking soda go in easier.  Then we poured the vinegar into bottles.  I helped the kids stretch the balloon top over the top of the bottle.  They lifted up the balloon making the baking soda pour into the vinegar.  The carbon dioxide that was created began to blow up the balloon.  Oh my goodness....it was so exciting!  I hope you have a big bottle of vinegar, because you can't do this one just one time.
