Non-Coalescence of Fluid Jets and Drops

Why in the world won’t these streams of liquid mix even though they are colliding? They are the same fluid of silicone oil, yet they just bounce off of each other.

This is because there is a thin film of air surrounding the jets of liquid, and the motion of the jets maintains the air-film barrier indefinitely.

A little bit like the way antibubbles work…
