Density Column Rainbow
Stacking liquids of different densities to create a colorful column
Demonstrate the concept of liquid density by layering immiscible liquids of different densities in a tall column.
Disappearing Beaker (Refractive Index Matching)
Making a glass object invisible by immersing it in a liquid of matching refractive index
Demonstrate the concept of refractive index by making a glass object disappear in a liquid that matches its refractive index.
Elephant Toothpaste
Rapid catalytic decomposition of hydrogen peroxide producing a massive foam column
Demonstrate the catalytic decomposition of hydrogen peroxide using potassium iodide, illustrating concepts of catalysis, exothermic reactions, and gas evolution.
Instant Freeze: Supercooled Water
Triggering instantaneous crystallization of supercooled water
Demonstrate supercooling by cooling purified water below 0°C without freezing, then triggering instant crystallization.
Non-Newtonian Fluid: Oobleck
Creating a shear-thickening fluid from cornstarch and water
Create and explore a non-Newtonian fluid that behaves as both a solid and a liquid depending on the applied force.
