Looking for something fun for the kids? I don't suppose it gets much better than this, the Bestway 16ft Dash N Splash Rally Pro Water Slide. Get it from Very where it's reduced from £40 to £16.
The Bestway 16ft Dash N Splash Rally Pro Water Slide comes with two surf rider inflatables that the kids use to skid along on. Each surfer has heavy duty handles on it so that little ones can hold on, I have always, always, always wanted one of these because they look like nothing but hilarity.
It is secured into soft ground like grass by six stakes. The water sprayer up the middle ensure kids get a slippery ride. There's a lower age limit of three on these but no upper one, so I reckon adults could use it too.
The spray feature works by connecting your garden hose to it, which means the water will be cold, so you'll need a real good day for this kind of slide. Two children can slide down this at once, meaning they can have a race.
