Terrarium Light

I have gotten the idea of making a light up terrarium mobile in my head and I’m not quite ready to give it up.  It has been brought up to me that I may have trouble dealing with messy wires that may make this project difficult.  I am hoping that I will be able to work around that issue by using conductive thread or yarn to hang the objects from my mobile.  I want to make a mobile that has hanging pods for air plants.  These pods will light up.  Here are a few photo inspirations:

I plan on sewing little pods to hold the air plants.  I also plan on making a push on-off switch that would be one of the elements hanging from the mobile.  Below are some material possibilities:
