We never really have the weather here for outdoor water parks, but in the US and other sunnier climates, they're very popular. 

Granted, we're old enough to remember the Rainbow Rapids in Dun Laoghaire, but there hasn't been much since. 

A record breaking water slide is due to be launched in New Jersey in the coming months. The slide is 90 feet high and "features" a vertical drop of 45 feet. It's so steep you have to get in a protective container to go through it. We want a go! 

The below video, made last year, gives a brief glimpse of what the slide will be like.
