I was playing around with particles and gravity, and this came up … lots of effects can be created by modifying the parameters gravity, friction, bounce friction, movement speed, etc. Here you can see the particles in a leak effect: it’s like water that’s coming through the side of a ship. By editing the horizontal movement speed for example you can control the force at which it blasts through.
