Pick a chemistry demonstration to play with your class. Each demo walks through ingredients, the reaction, and the result — step by step, with animation effects tailored to the reaction type.
Atoms come together and form something new.
Two hydrogen gases meet one oxygen gas and form water.
Play demoTwo lonely hydrogen atoms find each other and form a bond.
Play demoThree hydrogens grab one nitrogen to make ammonia, NH₃.
Play demoSodium gives up an electron to chlorine — and you get salt.
Play demoMagnesium ribbon ignites with a brilliant white flash.
Play demoFuel meets oxygen — flame, heat, and CO₂ + water.
A piece of carbon catches fire and becomes the gas you exhale.
Play demoMethane plus oxygen makes fire — and carbon dioxide and water.
Play demoEthanol (drinking alcohol) burns cleanly into water and CO₂.
Play demoThe fuel in propane tanks burns explosively in oxygen.
Play demoIons swap partners, salts form, hydrogen bubbles off.
Strong acid meets strong base. They cancel each other out.
Play demoA magnesium ribbon dropped into HCl bubbles vigorously.
Play demoA more reactive metal kicks hydrogen out of an acid.
Play demoAluminum rips oxygen away from rust — molten iron pours out.
Play demoMolecules pulled apart by energy — heat or electricity.
The nucleus itself changes — fusion, fission, and decay.
Two hydrogen nuclei slam together and become helium — like the Sun.
Play demoA heavy uranium nucleus splits in two — releasing energy and free neutrons.
Play demoAn unstable nucleus spits out a helium atom on its own.
Play demoFour hydrogen atoms fuse into helium — this is how the Sun shines.
Play demoThree helium atoms forge a carbon atom — how stars make life.
Play demoA plutonium atom splits — the fuel of fast reactors and Fat Man.
