“When people want clean water, they reach for plastic bottles,” says CrazyCap CEO Rakesh Guduru. “It’s bad for your health and the environment.” For those who want a more sustainable way to hydrate on the go, Guduru created a bottle cap that uses UVC light to sanitize water in just 60 seconds. The device has two modes, one to purify water from taps or public fountains, the other for streams and ponds—a potential godsend for hikers and campers accustomed to boiling their water or adding foul-tasting drops. The cap is rechargeable and compatible with most reusable bottles. Pricing for a cap-and-bottle pair starts at $69.99. —Simmone Shah
