title: Individual particles and physics in Sprite Kit
body: <p>I am a long time user of Stackoverflow but first post.</p>
  
  <p>My question is seemingly simple, is there a way to make particles from an emitter interact with the physics sprites in the scene? (For example, if I am using a particle for rain, and I want it to bounce or bumpy off a sprite of a man with an umbrella. There must be a way, but I don't see a lot of documentation on adding physics to individual particles. Any ideas?</p>
  
  <p>Thanks!</p>
