Cactus 'flesh' cleans up toxic water

The video explores the innovative use of cacti, specifically the mucilage, in cleaning polluted water and oil spills. Norma Alcantar, a chemical engineer, was inspired by her grandmother's traditional methods in Mexico. Her research, supported by the National Science Foundation, shows that cactus mucilage can effectively purify water, offering a sustainable and inexpensive alternative to chemical dispersants. Field tests in Haiti post-earthquake confirmed its efficacy. The potential for local harvesting of cacti for quick water decontamination after disasters is highlighted, showcasing a natural and innovative approach to water purification.
