This is a simplified experiment for the beginner and to get you started on the series set.
What you’re testing
How dissolved gas escapes a liquid system once it is exposed to lower-pressure environments.
Materials
- Carbonated drink (cola, sparkling water)
- Glass
- Optional: lid or cover
Method
- Pour the drink into a glass
- Leave exposed for 20–30 minutes
- Compare taste and bubble activity over time
- Stir halfway and observe acceleration
What you will see
- Rapid bubble loss at first
- Gradual flattening
- Faster degradation when disturbed
Why it works (simple explanation)
Gas molecules leave the liquid when pressure equilibrium is disrupted.
