It's big and blue and there's no missing the star attraction, Slip n Slide, at this year's Nottingham Beach. The Arrow, the largest inflatable urban waterslide in the UK, dominates Old Market Square.
At 55m long and 13m tall it towers over the sand, paddling pool, stalls and rides. And here I am about to give it a go. I can count the number of times in my life I've been on a waterslide on two fingers.
On one of those occasions a wardrobe malfunction as I splashed into the pool was the ultimate embarrassment. As work assignments go, this one fills me with dread. I'm not afraid of daredevil challenges: standing in the Globe of Death as motorbikes zigzaged around me and having knives flung my way were less daunting.
