In a scientific 'breakthrough', a team of scientists from the Indian Institute of Science Education and Research (IISER) in Mohali has developed 'green' crackers using distilled cow urine. Bladdering idea, these crackers made from cow urine are cheaper than the smoke-free, fragrance-based crackers out of plastic bottles developed by the same team last year. According to Prof Samrat Ghosh, a chemical scientist at IISER, the idea of using cow urine came due to the multiplicity of claims of its benefits, which the team decided to explore.
