To do this experiment we needed:
- Vinegar
- Bottle
- Paper funnel
- Baking soda
- Ballon
- Spoon
First we put vinegar into the bottle.
- Next we used a paper funnel to put baking soda inside the ballon.
- Then we attached the ballon to the mouth of the bottle.
- The baking soda and vinegar mixed together and made gas called carbondioxide.
- The carbondioxide filled up the ballon.
