Schlitterbahn Galveston is adding a new multi-million dollar set of slides that are more than the first of its kind - they are out of this world. Infinity Racers, which will open in June of 2019, is a pair of space-themed, head-first, racing slides. At a whopping 8-stories tall and as long as two International Space Stations, Infinity Racers deliver a fun, only one in the world, water slide experience. Both of the racing slides are nearly fully enclosed the entire time (except for the loading and splash zone) with multi-colored fiberglass that creates unique lighting effects inside each slide.
