For doing this wonderful experiment you will need two chemicals – Lead Nitrate and Potassium Iodide, a test tube, burner etc. Place a little Lead Nitrate and Potassium Iodide in two cups and then add water. Stir well with a glass rod so that the powders mix well with the water. 
Now add one solution to the other. You will be surprised that on mixing these colorless liquids forms a bright yellow solution. The color is startling yellow. 
Take some yellow solution in a test tube and hold it with a pair of tongs on a flame. As the solution gets heated the yellow color slowly disappears.
