moodboard for sting idea

For this idea I need to look at animated strings or tubes in 3D or 2D but I dont know if I will find images so I may have to look at videos instead.

 The images that I got from google were more what you would see in camera angles instead of actual pictures of what I could use, not saying its not helpful but it really does not give me the visual image of what I need to create this animation.
The best thing that gives me a visual of what I need is really the coca cola advert
