The Underwater Fireworks Thermodynamics Chemistry Demonstration Kit is an exciting demonstration sure to spark interest In the lab. Colliding bubbles of gas produce underwater explosions illustrating activation energy, combustion, and more.
Every day can be the 4th of July with this exciting demonstration. Colliding bubbles of gas produce underwater explosions. This demonstration shows how chlorine and acetylene gas can spontaneously react at room temperature. Safely conducted under water, this demonstration will spark student interest and allow you to discuss many chemical concepts. A one- or two-liter graduated cylinder and some glass tubing will be required. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.Concepts: Gases, activation energy, combustion, electron affinity, hydrocarbons, halogens.
Time Required: 15 minutes
Chemicals Provided: Hydrochloric acid, sodium hypochlorite, and calcium carbide.
Note: Perform this demonstration in a fume hood or well-ventilated lab.
