Narika Cloud Bottle – Cloud Formation Experiment Kit

The Narika Cloud Bottle is a compact, hands-on demonstration kit for exploring cloud formation, air pressure and temperature changes. Add a few drops of water to the bottle, use the hand pump to increase the pressure, then release the pressure to observe a cloud forming inside. The liquid-crystal temperature strip helps students investigate the temperature changes associated with compression and expansion.

Key Features

• Demonstrates cloud formation through changes in air pressure and temperature
• Hand-operated pump for pressurising the bottle
• Liquid-crystal temperature strip for observing temperature changes
• Compact 375mL PET bottle
• Suitable for repeatable classroom demonstrations of adiabatic compression and expansion

Specifications
