The Zinc Pyrotechnics Thermodynamics Chemistry Demonstration Kit provides students with a spectacular "fireworks" display. Water is added to a mixture of dry chemicals to highlight the concepts of catalysts and exothermic reactions.
This item can only be shipped to schools, museums and science centers
A spectacular “fireworks” display is initiated by adding two drops of water to a mixture of dry chemicals. Place a beaker with very small amounts of zinc dust, ammonium nitrate, and a catalyst in a fume hood. Add two drops of water to the mixture and watch as sparks, smoke, and excitement fill the air. Must be performed on a heat-resistant surface in a fume hood or outdoors.Enough materials are included to perform the demonstration seven times.
Concepts: Exothermic reactions, catalysts.
Time Required: 15 minutes
Chemicals Provided: Zinc dust, ammonium nitrate, ammonium chloride.
