Help Inflate deflate cloth Balloon

[Fenikkel]

Hi, we are trying to make a simulation in Unity similar to this video.

So, what we need is:

• Inflate and deflate the balloons
  
• Different meshes than spheres
  
• Collisions between the cloth meshes
  
• Compress the cloth meshes with the container (or some sort of colliders)
  

We didn't bought the Obi Cloth yet. It is posible? We only have this video as a clue.
There is some kind of demo to test if this can work?

Thanks.
