Before going through this, read the post about experiment 1 first.
As I was having fun with the vinegar and baking soda, I was also trying to blow a ballon, however it didn’t work but I decided to put it over the water bottle where the reaction was taking place and surely enough the carbon dioxide emitted by the reaction was used to blow the balloon ! Take a look!
PS: notice how the foam isn’t rising because the carbon dioxide cannot escape from the bottle and no oxygen is coming in either.
So this seems like the basic, simple experiment but it’s always been fun to see what happens and to learn the scientific explanation to what is happening.
What you need:
- dishwashing cleaner
- baking soda
- empty bottle
1. Pour 50 mL of vinegar and 50 mL of dishwashing cleaner into a cup and mix them together. You can add food coloring if you want.
2. Put this mixture in the empty bottle. The put the bottle in the sink.
3. Add a table spoon of baking soda. (If it doesn’t “erupt” right away, try adding more vinegar or baking soda.)
Baking soda is a bicarbonate (NaHCO3) and vinegar is an acetic acid (HCH3COO). When the two are put together, the react because of an acid-base reaction, this produces a lot of carbon dioxide (CO2) which will mix with the dishwashing cleaner and make lots of foam and bubbles.
My name is Roxanne this is my blog where you can find many different science experiments for educational purposes or just for fun. All are safe to do at home.
Currently 16, I’ve always been interested in science at school, and I recently started doing experiments at home. I’m learning new things and I hope you’ll be able to also through my posts!
