I think this is a great effect, and for the ending, well its a souveneir....2 permantely linked rubberbands. Ooberly awseome! I dont per-say own the effect, but i did manage to play around with the "goodies" included with the dvd at my local magic shop, this will go great with Slink, Crazy man handcuffs or any rubberband routine, cant wait to see the reviews!
Mind you, there are versions that you can make yourself, which are examinable, and can be given out to keep. The Flicking Fingers' Movie teaches one. But it will be nice to have pre-made ones which will be better than the ones you can make yourself.
no, exposing, would be saying what you did. they already say that it is pre-linked and they are selling refills. you are paying for the gimmick and method of performing/handling.
