This tool uses the POP Fan node to apply a wind field to particles matching a conical fan. The further away from the fan the particles are, the less they are affected by the force. For example, you could bind a fan to the front of an object and move it through particles to simulate something like a submarine moving through bubbles.

1. Create a particle system along the curve using the Location or Source shelf tools.

2. Click the Fan tool on the Particles tab.
