Color Chemistry Demonstrations
Perform chemistry demonstrations that produce colors or involve color-change chemical reactions.
Bead Tests
The borax, microcosmic salt, or sodium carbonate bead test may be used to help identify unknown metals. Learn how to perform and interpret the results of this handy analytical test.

Blue Bottle Color Change Demonstration
Learn how to perform the blue bottle chemistry demonstration, in which a blue liquid becomes clear, then returns to blue when swirled around. Instructions are also given for red -> clear -> red and green -> red -> green reactions.

Briggs-Rauscher Oscillating Color Change Reaction
The Briggs-Rauscher reaction, also known as 'the oscillating clock', is one of the most common demonstrations of a chemical oscillator reaction. Three colorless solutions are mixed together, producing a mixture that oscillates between clear, amber, and deep blue.

Flame Tests
A flame test is an easy experimental technique used to help identify a metal or ionic salt based on its emission spectrum when it is heated in a gas flame. Here's how to perfom a flame test and interpret the results of the test.

Halloween Reaction or Old Nassau Reaction
The Old Nassau or Halloween reaction is a clock reaction in which the color of a chemical solution changes from orange to black. Here's how you can do this reaction as a chemistry demonstration.

Water into Wine Demonstration
Turn a clear liquid into a red liquid, then back to clear again. This demonstration is commonly called turning water into wine or blood, and can be used to demonstrate acid-base indicators.
