- Rubbing alcohol

- Bottle (plastic) - with lid

- Matches

Method:

1.Pour a small amount of rubbing

alcohol into the bottle.

2.Light a match.

3.Hold your bottle under the match while squeezing

4.Blow out your match so it produces smoke, and release the bottle so the smoke is sucked into the bottle.

5.Immediately close the bottle tight with the lid.

6.squeeze bottle as hard as possible and release - The bottle should fill with a cloud.

Questions:

1.What does the rubbing alcohol do?Rubbing alcohol refers to either isopropyl alcohol (propan-2-ol) or ethanol based liquids, or the comparable British Pharmacopoeia defined surgical spirit, with isopropyl alcohol products being the most widely available. They are liquids used primarily as a topical antiseptic.

2.What happens when the air in the bottle mixes with smoke?What happens when you release them into water depends on what's being emitted. That water vapor, of course, just condenses, but we don't really care much about pumping water into the air anyway.

3.What does squeezing the bottle do to the air? Squeezing the air out keeps the CO2 in solution.
