It is an interesting handling of this old effect and certainly works very close up, with people breathing down the back of your neck! You do not need any special refills as any silk embroidery thread ( sold in skeins at all knitting shops) can be used,
I prefer the Flash T & R String by Henry Evan as sold by JB Magic, price eight pounds in which you ignite the balled up knot and it flashes to the restored 'string'.
There is a great 2 colour thread version in Shaun Yee's lecture notes and of course Geoffrey Buckingham put out his version in one of his books.
You probably would be best buying The Hindu Gypsy Thread book by Lewis Ganson, poublishe by Supreme magic and available form Magic Books By Post at £7:50p.
