You will need :

* 1 empty plastic soda bottle or water bottle

* 1/2 cup vinegar

* Small balloon

* Baking soda

* Funnel or piece of paper


What to do:

  1. Carefully pour the vinegar into the bottle.

  2. This is the tricky part... Loosed the balloon by stretching it a few times then use the funnel to fill it a bit more than halfway with baking soda. If you don't have a funnel you can make one using some paper and sellotape.

  3. Now carefully put the neck of the balloon all the way over the neck of the bottle without letting any baking soda into the bottle.

  4. Ready? Lift the balloon up so that the baking soda falls from the balloon into the bottle and mixes with the vinegar. Watch the fizz inflator at work!


How does it work?

The baking soda and the vinegar create an ACID-BASE reaction and the two chemicals work together to create a gas (carbon dioxide). Gasses need a lot of room to spread out and the carbon dioxide starts to fill the bottle, and then it moves into the balloon to inflate it.
