Builder handcrafts rollercoaster-like water slide in his back garden to beat the heatwave

A builder handcrafted a mega DIY water slide for his kids in his back garden - so incredible it looks like a theme park rollercoaster.

Mark Howell, 42, got busy with old decking he'd helped remove from a friend's home and transformed it into a water slide for his kids.

Lily Rayne, nine, and Welton, six, wasted no time using the mega water slide to slip down into the refreshingly cool water of their swimming pool.

Self-employed builder Mark even had a go himself.

Mum Danielle Brown, 43, loved watching her kids play and documented the epic make.

Travel business owner and mentor Danielle, from Tattlesworth, Lincolnshire, said: "When our new pool went up, the kids' existing slide didn't fit, so I asked Mark to sort a new slide, and a light bulb went off in his head.

"The result was this slide. It is lined with floor sponges - soft play mats - and then multiple layers of damp proof membrane.

"A sub pump brings the water up from the pool and down the slide to keep it cool and allow the children to slide easily down.

"He did it all in a couple of hours when I disappeared out for lunch!

"I was shocked when I got home, but then I saw what he created and absolutely loved it.

"He is incredibly innovative and we all think the slide is amazing.

"The kids have been using it ever since, and loved it today with Daddy home from work!

"We live in the village next to RAF Coningsby where the highest temperature is currently recorded at 40.3°C so this was well needed today!"
