I saw something on television once about this..
Apparently they packed the nozzle with a bunch of
drinking straws, or something very similar, to help
the water remain cohesive for longer squirts.

This was for a wider stream, perhaps 3-5 inches across.

This was just the last step in a more complex
preparation, I'm sure.

Of course, everything you see on TV must be true!
