Ever noticed the mountain of cups left behind at races? Kristina Smithe did—and she actually did something about it. After seeing the waste at a marathon, she invented reusable silicone cups and now rents them out to races. She’s already saved nearly a million cups from landfills! The cups are flexible, easy to clean, and way better for the planet. It’s wild that one runner’s annoyance turned into a legit eco-friendly business. #EcoFriendly #Sustainability #Innovation #Safety
