If you mean, by 'one of these', a section of the slide that forms a vertical loop of some sort, then yes.
If you mean, by 'one of these', a fully functional vertical loop that riders can go through every time without risk of horrible injuries or slightly smaller risk of outright death, then no.
Dude is wearing the most German bathing suit I can possibly imagine. There's an abandoned water park out here, I want to start a gang and have it be our hang out.
I remember going to this swim park in Germany called Palm Beach. It was about five stories high, with a lazy river inner tube ride that extended out of the building about halfway up, with no guard rails and a small drop at the end that bumps you up into the air.
3 people had died there up until the point we went, and the camp chaperone broke her arm that day.
