Virtual reality 

I was in the middle of the ocean current, the odd thing about it is, the depth of the water is only about 1 metre and I can see all the see creature clearly. I can even put my hand in and catch the fish, as I show this to my wife. I can scoop a few small fish,  and let it go again. I can see a few small turtle moving and swimming with the current. That’s the end of that part.
