A US man who calls himself Professor Splash has broken his own world record by diving from 36ft into a children's paddling pool.
Darren Taylor, the world's greatest and most decorated shallow water diver, dives into just 12 inches of water, reports the media.
Mr Taylor, from Denver, Colorado, uses a specially adapted diving technique to lessen the impact of his body on the water by spreading it out.
Throwing out 137 gallons as he hit the freezing water in Trondheim, Norway, the jump was Mr Taylor's 13th Guinness certified record.
He said: "The bottom of the paddling pool is not inflated, because that would be against Guinness rules.
"However, there are a couple of foam mats underneath the pool. Believe me, jumping and landing as flat as possible in 12 inches of water is tough enough as it is."
Mr Taylor was in Norway performing as entertainment for the International Association for Exchange Students.
He added: "I like the water to be as near to freezing as possible. That way the water is dense without being freezing and helps to slow my descent when I impact the water.
"You have to judge the wind, the cold, the time of day and become calm so that each jump is a success.
"With my unique technique I can make each jump a world record one, but I must admit they are not getting any easier."
