Home Experiments
Real chemistry with household materials. Every experiment lists safety notes, a full procedure, what to observe, and the explanation behind the result.
Baking soda and vinegar neutralization
Mix baking soda and vinegar to trigger a fizzy neutralization reaction and test how the mixture's acidity changes.
ExperimentBalloon gas laws
Heat and chill a balloon to watch Charles's law inflate and shrink it, then squeeze it to feel Boyle's law.
ExperimentCartesian diver bottle
Build a Cartesian diver from a ketchup packet in a water bottle and make it sink and float with a squeeze.
ExperimentCandy dye chromatography
Separate the hidden dyes inside candy shells and markers with paper chromatography using only water.
ExperimentDensity tower of liquids
Pour honey, soap, water, oil, and alcohol into one glass and watch them stack into a floating rainbow of density layers.
ExperimentSplitting water with a 9V battery
Split water into hydrogen and oxygen with a 9V battery, pencils, and baking soda in this strictly supervised classic.
ExperimentElephant toothpaste, small and safe
Turn ordinary 3% hydrogen peroxide into a gushing column of foam with dish soap and yeast in this small-scale, supervised classic.
ExperimentEndothermic chill with baking soda
Mix baking soda with citric acid in water and feel the cup get cold as the reaction absorbs heat.
ExperimentHand warmer crystallization
Trigger a reusable sodium acetate hand warmer and watch crystallization release real heat you can feel.
ExperimentRed cabbage pH indicator
Boil red cabbage to make a natural pH indicator, then test household liquids and watch the colors reveal acids and bases.
ExperimentWhat makes nails rust
Leave iron nails in air, water, and salt water for a week and discover exactly what rust needs to form.
ExperimentPolymer slime lab
Cross-link school glue into stretchy slime with contact lens solution and explore polymer networks hands-on.
ExperimentSoap the emulsifier
Shake oil and water apart, then add dish soap and watch an emulsion hold them together like magic.
ExperimentSugar solubility versus temperature
Dissolve sugar in cold and warm water to discover that temperature changes how much solid a liquid can hold.
