This setup simulates a rocketlaunch with Storms Smoke Solver.

This setup divides particles randomly into 3 groups. These groups are then affected by different forces to divide them into 3 piles.
This setup creates a balloon with a line and emits multiple instances into a cloth sim.
This setup creates a sparkler with dumbparticles for the sparks and a smoke sim on top.
This is a whole project with 3 separate scenefiles.
1. Creation of a custom force with smoke sim
2. Softbodysimulation for the stem
3. Creation and simulation of the dandelion seeds
You need to run them one after another to get the needed caches.
This setup combines two cloth sims, one for the fabric and one for the yarn. It also creates a dynamic guide for the yarn which follows the fabric.
This setup uses a collider to unstick particles from another spinning collider to give the impression of a piece of wood beeing cut on a lathe.
This setup uses smoke and dumb particles to create a spraycan effect. It also contains a useful node combination to create a radial emitter for particles.
