|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
