How did he pull that off?

There is a glass frame in the pool. The swimmers are there to keep the water unstable so the glass frame can remain invisible. The swimmers can swim under his feet because it’s a frame.

That guy stepping on something look again

Plexiglass columns. Watch! He knows exactly where he is stepping. The glass are transparent, not visible to the eye in water.

Naaah...there's definitely transparent glass frames beneath cos he's very conscious of his steps and where to step on. I also believe the swimmers are part of the distractions so that we the viewers can't see the glass frames beneath the water. It's a very creative one though

I’ve seen enough, name him the new Messiah!!

This is how…. 🌚

For the fact that his left leg stays the same position with the right after he makes a move, man is standing and staggering on a glass frame invisible to the eye kuz it’s underneath the water
