Fizz Inflators

We had great fun on Thursday blowing up balloons using vinegar and baking soda.  The acid vinegar reacts with the alkaline baking soda to produce carbon dioxide bubbles.  Because gases require a lot more space than liquid so the carbon dioxide fills the bottle then moves into the balloon and inflates it.  You might like to try this at home and see how varying the amounts of baking soda and vinegar affects the amount the balloons inflate (a word of warning - we had a couple explode!)
