3. World’s Longest Tube Waterslide.
The Magic-Eye at Galaxy Erding water park is the longest inner tube waterslide in the entire world. Magic-Eye’s record-setting length is complemented by its 22-meter (72 ft) height. The tube slide features a distinct interior distinguished by continuous seemingly glowing lines that create an unmatched viewing experience while riding. The design can be overwhelming to some patrons due to its strobe-style effect, which could arguably be potentially fatal if someone with epilepsy were to ride the waterslide alone.
