Teach cloud formation when there’s not a cloud in the sky! This apparatus duplicates atmospheric conditions during cloud formation. It consists of a special glass flask with a rubber hose connection, pinch clamp, and large, thick walled, rubber bulb. When the atmospheric pressure is lowered, smoke particles are introduced into the chamber, and a nucleus for the formation of water droplets is produced. By compressing and suddenly releasing the bulb, a dense cloud forms in the flask.

Features:

• Cloud-forming apparatus shows how clouds are formed
• Includes detailed instructions on how to operate the apparatus
• Approximate size of apparatus: 10.25in. X 6.25in. X 6.25in.
• Excellent for use in a classroom setting or as part of a science fair project.
