Hydrogen peroxide is added to a solution of sodium potassium tartrate and heated. Copper sulfate solution is added and the solution turns light blue. With continued heating the solution foams...
Calcium carbide is placed in a cylinder containing water. A reaction occurs producing acetylene gas bubbles. A plastic tube from a chlorine gas generator is placed in the cylinder. As...
A small amount of potassium permanganate is placed in a petri dish. A few drops of glycerin are added and after a few seconds, a puff of smoke and violet...

For this demonstration, add hydrogen peroxide to a colorless solution of potassium iodide to produce a red color, or you can add the hydrogen peroxide to a purple solution of...
You will be able to demonstrate the principles of a redox reaction. Paint the potassium thiocyanate solution and potassium ferrocyanide solution onto a filter paper. Once they are dry you...
Make your own foam and explain how when two viscous liquids are mixed together, they initiate a reaction producing a light weight polyurethane foam which expands to 30 times the...
Explain how there are exceptions to the rules of chemistry. Heat a solution and watch it form a precipitate. Watch it go back into solution as it cools.
Construct a simple wet cell battery. When complete it will generate 1.5 volts for 20-30 minutes. Several cells can be connected in series to increase the voltage or in parallel...
