A new water purifying cup is making it possible for people to drink safe, clean water from creeks and streams. The cup, developed by a team of scientists from the University of California, San Diego, uses a combination of ultraviolet light and ozone to purify water and make it drinkable. The cup is small, lightweight, and portable, making it ideal for hikers, campers, and travelers who need a reliable way to purify water in the wilderness. The cup is also easy to use, requiring nothing more than a few drops of water and a press of a button. With the press of a button, the cup will emit ultraviolet light and ozone to purify the water and make it safe to drink. The cup is an innovative and effective way to ensure access to safe drinking water in remote areas.
