Using the Engine on User Events (Touch Taps)

[indivisable]

What would be the best way to achieve this effect (in an optimal manner); User taps on screen and particle system puts fireworks under where the user taps, I am trying to test to see if I should create a new particle system object each time or keep one overlaid on UI (with disabled interaction).

Does anyone have any advice here? Also beyond user events my UI can dispatch events to place a particle event at any given location on screen. Similar to touch I'm wondering what is most optimal way to do this.
