I did this but used some old artificial flower stems that had a wire inside. Just another idea if you don't have whatever the black things are in the video.
I absolutely think this is adorable but it would be nice if you could put a listing of the things you are using such as the black things on the side of the bridge however I still enjoyed this video
If you live in a country where they do not have glue guns you can purchase one on Amazon most likely you could find one that matches up with your electrical outlets but if you cannot many countries have Transformers
