Cow urine generates a cracker of an idea

A team of scientists from the Indian Institute of Science Education and Research (IISER) in Mohali has developed 'green' crackers using distilled cow urine. 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.
