Ms. O’ Donovan’s Room 12 makes Carbon Dioxide

on November 9, 2018



MATERIALS: bread soda, vinegar

APPARATUS: balloon, a bottle


STEP ONE; Pour the vinegar into the bottle. Pour in enough to fill a quarter of the bottle.

STEP TWO: Put 4 teaspoons of bread soda into the balloon.  Next, attach the balloon to the bottle.

STEP THREE: Be sure the balloon is facing upwards. Last stand back and wait! (You may need to stand near a sink for this!)

RESULT: We discovered that the bread soda mixes with the vinegar to make a gas called carbon dioxide CO2.  This gas blows up the balloon for a minute or two. This happens because the bread soda is mainly made of sodium, hydrogen, carbon and oxygen. The vinegar changes the parts causing a gas to be released which inflates the balloon.

Here are some photographs of our experiment!
