Falling through water to a new free diving world record

posted by Jason Kottke   May 03, 2016

Yesterday, New Zealand’s William Trubridge set a free diving world record in what’s called the free immersion apnea discipline. According to the official results, Trubridge dove, without using fins or weights or tanks, to a depth of 124 meters in Dean’s Blue Hole in the Bahamas. The video above offers a view of most of the dive, which took 4 minutes and 24 seconds for Trubridge to complete. I don’t know a whole lot about the mechanics of free diving, so I was surprised that after a few pulls on the rope to get himself going, it’s a free fall to the bottom. Watching him falling motionless through the water like that was eerie.

Update: Thanks to @chriskaschner for the diving physics lesson:

Below ~25m your lungs compress from pressure and you “fall” underwater, no more floating, only way back is to swim/ pull up
