Card on Ceiling trick has been around for many decades and was originally
performed with tacks but over the last few decades, magicians have been
using wax as an alternative.
PropDog they came up with what they think is a great improvement to
the wax and that is to add color to it.
has many advantages depending on how you perform the effect. For example
if you use a method where you store the wax in a tub, then you can use
either Bicycle Red or Bicycle Blue wax and once on the card, it will
be far more invisible. This way, if you were to accidentally flash the
top of the cards whilst performing the trick, it is far more unlikely
that the spectator will notice the wax.
magicians use a method where they store a tiny ball of wax on the end
or the lid of their Sharpie, so we came up with the idea of coloring
it to match the Sharpie. This way, the ball of wax is completely un-noticeable
and stolen as you recap the Sharpie.
Sharpie Lid Black is the exact color match for the Sharpie lid, so will
not be noticed by a spectator and is also great if you store your wax
on your belt... if you're wearing a black belt that is.
same is achieved with Sharpie Grey if you want to store a wax ball on
the bottom of your Sharpie.
