Wondering if this is simply a reversed video. I think I understand the idea of like specific gravity. The coloured fluid floats because it has the same density as the water. But the reverse of the rotation bringing it all back into the same blob. Hmmmm.

T differing fluids each having approximately the same specific gravity and or density none of which are able to emulsify with the other OK that part can be real, but I take issue with the red and green fluids being returned into their original blobs right down to the tail left by the syringe

I have a hard time believing it also. But I looked frame by frame.



There is no frame at the beginning that looks close to the last frame.

I know, I even did like you did but instead of watching the blobs I watched the hands when the hand is returned to the table where the translucent white object is the position of the arm does not match the placement of it at the beginning. I still have a doubt of the validity because seeing is not always believing unless I can witness it live in real time while it is happening, even then I don't always trust my eyes. Magicians make their living on visual deceptions

Interesting dissection, all the video presenter need do is dissolve or fade in a couple frames. Maybe both.

To the sceptics. I would suggest that you might consider what would happen if these were liquids with high viscosity. It is a genuine demonstration.

[Elizabeth Greene]

I'm unable to accept this reality at this time. Please reset the universe and check back again later.

Is the secret sauce here that the density of the liquids are the same but they can't mix?

(She says, knowing that the next couple of hours are going to be on YouTube taking this apart piece by piece.)

I thought we decided from our investigations that the demonstration was real.

I believe all of our skepticism is healthy. Many of us have a "trust but verify" attitude. We must all be very aware how very easy it is to manipulate sound, photos and video now. Hearing and Seeing is not always believing today.

In regard to considering, "what would happen if these were liquids with high viscosity", it appears to me that they do have a high viscosity.

While the liquids aren't revealed, there is a difference between mixing, soluble-insoluble, solutions and emulsions.
First one I remember, the original water soluble cutting oils. Another bit of amazement is water and alcohol; two equal quantities result in less than logical volume. They not only mix, but integrate.

Think we'd agree both knowledge and skepticism are healthy viewpoints.
