City Slider: Hobart CBD turns fun park with huge temporary water slide

Hundreds of people have flocked to Hobart's main street to try out a huge temporary water slide.

The City Slider - a 325-metre long, six-metre wide waterslide - has taken over Elizabeth Street in the CBD for a day before heading interstate.

The slide has already made appearances in Launceston and Devonport and will be taken to Queensland next on its first national tour.

Co-founder Stuart Harris, whose company is based in Hobart, said the slider turned a childhood dream into reality.

"I think everyone when they were young wanted to extend their waterslide and everyone wanted the biggest waterslide possible and so we've kind of brought that to them," he said.

"It all started in Hobart and we're now just getting ready to tour it around Australia, looking at doing 30 dates this year.

"We run 3,500 people through the slide over a course of 12 hours and people generally get sort of five, six, seven goes on it and yeah, lots of smiling faces."

Hobartians gave the slide a big thumbs up.

"Absolutely awesome, fantastic, yep, great enterprise, brilliant, kids loved it. I loved it more," said one mother.

The City Slider will be open until 10:00pm.

Another massive water slide, known as Slidestreet, toured Australia in December and January, taking over city streets in Perth, Adelaide, Melbourne and Sydney.
