This is a little experiment with using a couple of tricks to get particles to behave the way I want them to.
What you see in these videos is a particle emitter floor that has shot up the sprite bubbles into the air with a high drag value. The choreography has no gravity, so when the darg slow the particles down, they suspend in midair. I have 2 foces attached to the hose model. A cone shape with a negative force and a sphere shape also with a negative force. What this does is that all particles within the cone shape get drawn in, and the sphere shape force will hold them in the center of the hose.
My first tests showed that if I only have the cone, the hose would leave a trail of bubbles at the height of the cone force. I will do a step by step tutorial if there is enough interest.
