Universal Indicator Rainbow
This hands-on activity, which is part of the ACS-Science for Kids collection, explores a simple acid/base indicator. Students use household solutions of acid and base to change the color of the indicator.

A Gas Sudsation
In this investigation, students add some soap solution to an empty bottle. They add some baking soda and vinegar. A chemical reaction between the vinegar and the baking soda produces carbon dioxide gas. The interaction between the gas and the detergent creates bubbles. These bubbles have more staying power than the bubbles created by just vinegar and baking soda. With the right amount of each ingredient, students should be able to control the reaction and get the amount of bubbling they are looking for.
