This is the second time we've worked with Kriss and he certainly hasn't changed. As expected, Kriss brightened up the studio with his infectious laugh and never-ending smile.

He's so passionate about The Big Tap Challenge and really got us thinking about how much water we waste every day.

He was such a joy to work with; friendly, funny and just generally fantastic. I still can't believe he's in his fifties!
