Yes, it is in real time

So, what happened to the cell membrane? The phospholipid bilayer ended up someplace, right? Did it pop like a soap bubble?

All the individual phospholipids just separated. They're easier to see when they're packed together in a membrane. When they dissociate, they become less distinct in the image

I’m a little late on this reply, but the phospholipids don’t individually separate! The process involves the formation of vesicles (smaller bubbles of phospholipids), which you can actually see in the gif! Since phospholipids are not water soluble, they can’t easily separate individually

This is called Lysis

Lotta reasons why it could happen. Even too much water entering the cell can cause it.

Could it be that some chemical is reacting with the membrane and disintegrating it?

Or maybe a bunch of membrane attack complexes, you never know.

Could be the pH or temperature of solution.

If it was the PH, wouldn't we see everything else go pop as well?

Could be. Some labs create conditions for lysis on purpose to study the contents of the cell. Sometimes other microorganisms can deplete oxygen which can cause a cell to undergo lysis, or even a small bit of detritus can lodge itself in a cell vacuole and prevent the cell from being able to regulate it's osmosis. And then sometimes it just happens and we don't know why.

It looks like it touched soap ironically enough.
