Product Description

By: The Flinn Staff


Put an exclamation point on your year-end review of chemistry concepts with this electric, entertaining, patriotic set of five demonstrations!

• Passing electric current through a solution produces streaks of silver crystals that reverse course when the polarity is switched.
• Mix milk of magnesia with universal indicator and observe a colorful show when the antacid dissolves in simulated stomach acid.
• Take two rusty iron balls, wrap one in aluminum foil, then bang them together and observe the fireworks in this safe variation of the classic thermit reaction.
• Mix three sets of two colorless solutions and, in 30 seconds, the solutions flash red, white, and blue in a tribute to the grand old flag.
• Add a pale solution to Uncle Sam's topper, then hold on to your own hat as red, white, and blue foam erupts from the stars and stripes adorned stovepipe.

Concepts: Oxidation-reduction, electrolysis, pH indicators, acid-base neutralization, activation energy, exothermic reactions, buffers, solubility and equilibrium, clock reactions, catalyst, decomposition reactions.
