The basis of all “fireworks” like effects (or rocket boosters!). Essentially, a single point with @v = {0, 1, 0} fed into a POP Replicate with Impulse set to $F%24==0 e.g. points are replicated every 24-frames.

A POP Force is a pushing force – it accelerates particles – each step adds to the particle’s @v. A POP Wind is a pulling force. If we have this setting: An attribute is created on the particle called @targetv – in this case {0,2,0}. Over time, the particle will match its own @v to @targetv. This also means that the particle’s @v will never exceed @targetv – as apposed to a POP Force, which keeps adding to @v.
