We all know swimming in a dirty river is a bad idea and can cause health problems. But what about swimming in a pool ON the polluted river??? The designers and team behind +Pool saw that no one swam in New York waters, so they decided to do something about it. They came up with +Pool. A pool designed to filter the river it floats in through its walls. How cool is that?! According to the website, "+ POOL is designed to filter the very river that it floats in through the walls of the pool, making it possible for New Yorkers to swim in clean river water for the first time in 100 years. The layered filtration system incrementally removes bacteria and contaminants to ensure nothing but clean, swimmable water that meets both city and state standards. No chemicals, no additives, just natural river water. " The team is still working out the kinks, but they have a mini version out on the river right now! It's going to be on the water for 6 months so the team can observe the pool working in real conditions. Another cool thing about this pool, is that you can have your name on it! The team raised money, by allowing people to personalize tiles. You can do so here. I can't cover the complete awesomess of the +Pool because I could literally go on for pages and pages, so just check out their website for more information.
