YEN FOR YELLOW - ENGLISH - 17MB.wmv

Place a little Lead Nitrate and Potassium Iodide in two different cups. Add water and stir well. Now add one solution to the other. Surprisingly the colorless liquids will turn a bright yellow. Heat the solution in a test tube on a flame and the color slowly disappears. This work was supported by IUCAA and Tata Trust. This film was made by Ashok Rupner
