haha thats cool.it happened because IT IS NOT WATER.it is CORNSYRUP which is very thick.he spun the liquids one way and spun them reverse the exact same way so they went back to where they were in the first place.it all a matter of science lmfao

It is just water and the injected red stuff is water with red dye in it. There is this videos's brother on YouTube called "turbulent flow".

A low flow rates the layers of liquid flow over each other neatly and the dye slides between them. At higher flow rates, the shear between the different layers causes rotation in the flow this is the mixing.

The whole thing was sorted out by Osborn Reynolds in 1883.

These fluid dynamic effects are vital for planes flying, and other such stuff.

You can also get the laminar and turbulet effect from a tap. The glassy flow is laminar, the cloudy, turbulent (not dissolved water).

With non-mixing taps at the same flow rae you can get laminar from a cold tap and turbulent from a hot one, but don`t get me started

IkeRay above explained it correctly. Both liquids were corn syrup. Only the ones added later was dyed different colours. So all liquids have the same density.

Now if it was moved slowly, and returned back slowly all particles will come back to their original positions, including the dyed particles.

You will note that there were 2 people holding on to the jar to make sure that there was no movement on it. This was so that all particles could align correctly.

i think it's because the dyes have different densities explains why they stack onto each other.
