Weird MCPE Glitch

Makes a ocean mysteriously disappear!!

Step 1: Create a New World (Or Not)

It really doesn't matter... Just get onto a world.

Step 2: Build a Platform at Sea Level

I think it has to be 3 blocks wide, I don't know.

Step 3: Drop Into the Unknown

Step 4: Get Underneath

Now swim until your head hits the underside of the bridge.

Step 5: Press Against the Bottom

Just press your head to the bottom of the bridge and swim around a bit... Eventually you'll see the ocean disappear for a second. Repeat until you locate the exact spot where the ocean disappears. Take a screenshot quickly. ( home & off button pressed simultaneously )
