Directions

Fill your soda bottle with enough hot water to cover the bottom.
Have an adult light a match, let it burn for a second or two, and then drop the match in the bottle so that smoke fills the inside.
Quickly place the cap on the bottle tightly, so no smoke escapes, and shake the bottle.
Squeeze the bottle hard to increase the air pressure. Release the bottle to lower the air pressure. You may need to squeeze and release a few times.
Wait a few seconds and watch your cloud form. You may need to hold your bottle against black paper to see the cloud.

Questions:

    Why do you shake the bottle?
    When you squeeze the bottle and increase air pressure, does it cool or warm the air?
    When you release the bottle and decrease air pressure, does it cool or warm the air?
    What do we call temperature changes caused by changes in air pressure?
    What does the water vapor inside the bottle condense upon?
