Three 16 year olds watched a child drink from a plastic container. What they invented next just won a global prize.
Avyana Mehta, Ariana Agarwal and Vivaan Chhawchharia (all 16) are the first Indian team to win The Earth Prize, the world's largest environmental contest for teens, chosen by 23,000 public votes (May 29, 2026).
Their invention Plas Stick, a biodegradable powder from waste tamarind seeds, makes microplastics in water clump together, ready to be pulled out with a handheld magnet. No electricity, no filter system needed.
The idea was born on a village visit, watching a child drink from a communal plastic container. Their workshops have already reached more than 8,000 people across India.
