Want to walk on water? Then check out this cool new Aqua Treadmill from World of Watersports. This giant inflatable wheel lets up to 3 people walk, crawl, climb, tumble, or just chill out inside it anywhere from a backyard swimming pool to the ocean. It features sprockets along the outer wheels that help propel it forward at speeds up to 10 mph, can be easily steered just by shifting weight, has high-visibility colors, and has 8 built-in drainage ports to keep it from filling with water. The only downside is waiting 15 minutes for it to inflate. Check out the video below to see it in action.
