Crazy German Water Park

We've read about this huge indoor water park that was built in a hangar a few years ago but there wasn't a detailed video of it at the time. Now there is - with a father and his son and it's viralling...

Did You Know... The hangar – the largest free-standing hall in the world – was originally designed to protect large airships from the elements. The Tropical Islands Resort, as it is called, is home to the biggest indoor rainforest in the worldand is open around the clock, every day of the year. Inside the hall, the air temperature is 26 °C and air humidity around 64%!
