Inflating ballon

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.
