Product Description

By: The Flinn Staff

Quench your students’ thirst for knowledge with a fountain of surprises in this guided-inquiry demonstration. The fountain appears to require no energy to run—defying the laws of nature. Marvel as Hero of Alexandria did 1900 years ago when he used air pressure changes and compressed air to lift water. As the solutions flow and mix, a beautiful rainbow of colors emerges. Varying acid and base concentrations change pH levels to create new color patterns each time! Use this versatile demonstration multiple times when teaching acid–base chemistry and gas laws. Detailed instructions include student questions and answers for the teacher. Enough materials are included to perform the demonstration seven times.

Concepts: Air pressure and vacuum, acid–base chemistry, pH and indicators, neutralization.
Time Required: 10 minutes
Materials Provided: Fountain connector, hydrochloric acid, sodium hydroxide, universal indicator, universal indicator chart, 2-L soda bottles, and Beral-type pipets.
