Just when we thought the home water slide, otherwise known as a “slip and slide” in the late 80s, couldn’t get any better, well, it just did. The Banzai Aqua Blast Dual Racing Slide lets you and a friend race to the finish, which features a finishing flag. The first to grab it wins. Included are two inflatable body boards to increase the speed and hopefully the experience. It features dual water-spraying tunnels and splash pool with water-filled rim. Summer fun costs just $24.99.
