The fizz inflator, By Sophie

The fizz inflator

This week was New Zealand Science Week so our hub did a three experiments on the 17th of may. They were all very fun.

One of the first experiments was called the fizz inflator. For the fizz inflator, we used, Baking soda, Vinegar, an empty bottle and a balloon.  

Firstly, we put the vinegar into the empty bottle. Did you know that vinegar can be used for a range of useful jobs, eg, make flowers last longer(vinegar prevents bacteria growing), wash away stains, etc. Anyway, next we poured the baking soda in the balloon. That was so the we could place the balloon on in time.

Afterwards, we had to place the balloon on the bottle. We tipped the baking soda into the bottle ( it's in the balloon already, remember). When the baking soda got tipped in, the mixture started to bubble immediatly.It was called a chemical reaction.The mixture then inflated the balloon up. It was because the mixture created carbon dioxide(gas/C02) which inflates the balloon.Baking soda actually makes a lot of food rise,eg., bread, scones, etc.

This experiment was really fun. I learnt a lot about science in this activity and I would definitely recommend you to try it if you want to learn more about science!
