Cartoon illustration of water-purification machine.

“To make the world a better place, I invented a transformative water purifier. It takes in dirty and polluted water from rivers, lakes, and even oceans, then massively transforms the water into clean, safe and sanitary water, when humans and animals drink this water, they will live a healthier life.”
– Audrey Zhang, 11
