Materials

Large clear plastic soda bottle with screw-on cap

Squeeze bottle with long plastic hose

5 different color pens

Dark-colored construction paper

Wooden matches

Safety glasses

Create a Cloud in a bottle

No water What change did you

Air pressure influences the formation of clouds in the atmosphere.

Valve stem

Drill

3/8-inch drill bit

2-Liter Clear Plastic Bottle with cap or stopper

Matches

Water

Foot pump

Safety goggles

Tips and warnings

To reverse the cloud formation, re-stopper and pump air into the bottle.

The use of safety goggles is strongly recommended.

Over pressurization of the bottle may cause it to rupture or explode

Further investigation

What effect does water temperatures have on the cloud formation?

Does the size and type of particle make a difference in cloud formation? (smoke from a candle, chalk dust, talcum powder, etc)

Using a slide projector or strong flashlight, shine some bright light through the bottle and view the bottle from various angles. The scattering and diffraction may cause different colors to emerge, and these colors can change.
