the only way that this would look fair to me (as a magician) is if you let go of one rubber band while they are linked so that I could see that it's not a 'double link' with one half covered. I know of several impromptu rubber band links that look a lot more realistic, but this would be amazing if you could show both entire bands not linked, then after the link occurs, drop one down to really show linkage, and then unlink them. Just that one subtle difference (if possible) would make this look so much better to me.
