**Title:** Making Homemade Sparkling Water with Vinegar and Baking Soda
**Objective:** Create sparkling water without a CO2 cylinder using a DIY method.
**Method:**
1. Generate CO2 by mixing vinegar and baking soda in a bottle.
2. Transfer CO2 to a bag, then to a separate bottle containing water using a makeshift system (including a tire nozzle and ball-inflating pump).
3. Shake the bottle to dissolve CO2 in water.
**Key Takeaways:**
* Initial attempts failed due to air in the system and inadequate CO2 pressure.
* Success achieved by:
+ Minimizing air in the system.
+ Using cold water (ideally ice water), as CO2 dissolves better in it.
* Result: Homemade sparkling water with a light baking soda base and acidic taste (due to carbonic acid formation).
**Safety Reminder:** Wear protective glasses when attempting this experiment at home.
Here are the key facts extracted from the text, numbered and in short sentences:
**About Sparkling Water**
1. Sparkling water contains carbon dioxide (CO2) dissolved in water.
2. CO2 in sparkling water is the same gas found in soda and exhaled by humans.
3. CO2 dissolves in water under pressure, creating the "fizz" effect.
**Commercial Sparkling Water Production**
4. Commercial sparkling water is made by injecting CO2 into a sealed bottle of water under pressure.
5. Machines that inject CO2 often require replaceable CO2 cylinders.
**Experiment Setup**
6. The experiment aims to create sparkling water using vinegar and baking soda to generate CO2.
7. A tire nozzle, hose, and plastic bag are used to capture and transfer CO2.
8. Baking soda and vinegar react to produce CO2, which is then injected into a water-filled bottle.
**Experiment Findings**
9. Initial attempts resulted in a "tire tube" taste, likely due to air contamination.
10. Reducing air in the system and using a more efficient CO2 transfer method improved results.
11. Shaking the bottle increases the contact area between CO2 and water, aiding dissolution.
12. Cold water (or ice) significantly improves CO2 dissolution in water.
**Successful Outcome**
13. After optimizing the process, the experiment successfully created homemade sparkling water.
14. The resulting water had a light baking soda base and acidic properties, similar to commercial sparkling water.
15. The acidity in sparkling water comes from carbonic acid, a product of dissolved CO2.
