Loving magical arts for over 25 years,I would like suggesy that Rubberneck has two great qualities
to it:
1) Simplicity of method however demanding physical dexterity training of fingers,
which is entirely positive for any lover of impromptu magic.
2) As a beginner, this effect
allows you to connect your fingers to work for you. For seasoned magicians your imagination mixed
with this illusion is endless!
Thank you Dan for your great work!
