Disappearing Ink Demonstration

Expose your class to the science behind acid-base reactions through the demonstration of an ink that disappears - right before their eyes. You'll apply a blue liquid to a piece of cloth, leaving behind an "ink" stain. However, in a few seconds the blue spot fades and eventually disappears. Explore the chemical bases behind this phenomenon!

Provides a safe, quick and easy demonstration of a key chemical concept. Makes a great introduction or reinforcement of a topic. Demonstration comes complete with everything necessary to perform it, including complete, step-by-step instructions and enough materials for multiple demonstrations.

Recommended for students in grades 7 through 12. Manufactured by Neo/SCI.
