Equipment

-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 tiet with the lid.

6.Squeeze bottle as hard as possible and release-

The bottle should fill with a cloud.

Why?

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? E.g. smoke released from factory chimneys if directed towards a water body or container, will it dissipate or curb pollution?  Has there been any experiments done so far?

3.What does squeezing the bottle do to the air?
