This setup creates a gravity defying ribbon.

This setups cuts shapes out of a basemesh and converts them into inflated balloons.
This setup creates a balloon with a line and emits multiple instances into a cloth sim.
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.
