My understanding is that the Kaye effect occurs in shear thinning liquids, and I'm not sure that silicone oil fits that category. Is the same effect at work in all these videos?
I suspect that it is the same effect. He isn't clear what fluid the jet is in the first part, but near the end he mentions pouring mineral oil into a pan of the same. Both mineral oil and silicone oil are polymeric fluids, and will most likely display shear thinning behavior. I suspect the main difference between this and the shampoo videos is that here the jet is a much larger diameter and therefore has more momentum, deflecting the surface and setting up the bounce. In the shampoo videos, the jet doesn't have the momentum to displace the surface, and so only starts to jump as the material settles. Note that the bounce occurs as the flow rate of the jet decreases, so presumably there is an energy balance between surface tension and momentum (maybe viscous forces as well?) that determines whether the jet simply pierces the surface, or sets up the bounce.
Thanks for the sift, I'll probably spend the rest of the day looking into this more instead of doing the research I should be.
