Thanks for the comments!
Yes, it does require some form of gimmick. The method is very different from the usual linking bands. Those familiar with Daniel Garcia's Rubbermade or Nabil Murday's Link! will be able to see that I'm not using the same method in the my Fusion Bands. My method has no clothing restriction, and works in all angles and lighting conditions.
For most linking rubberbands effect out there, the rubberbands were linked for a short while and the magicians have to unlink the rubberbands. The audience will feel that they just witnessed a good illusion.
Fusion Bands on the other hand allows you to hand them the permanently linked rubberbands to keep as a souvenir. This is when the illusion becomes reality.
