pH Indicators — The Color Chemistry Kit

Ever wonder why lemon juice tastes sour but baking soda tastes bitter and what chemistry explains the difference? With five professional-grade pH indicators and eight everyday household substances, this kit turns your kitchen into an analytical chemistry lab. Watch solutions shift from vivid yellow to deep blue to hot pink as you build a complete pH map of the world around you. Discover that milk isn't neutral and that your own tap water tells a chemical story. Stunning, colorful, and genuinely educational this is the experiment that makes students say "wait, this is actually chemistry?"
