This trick is really good for state magic I find. The way I like to do this is to first put some
yellow soap in along with the fake yoke, or even a real egg yoke. Usually when the silk disappears
people are amazed, but there are always skeptics who will call out that it's a fake egg. I love when
people do this. At that point I pull the silk out and confirm their claim. This is when you just do
some magical wave and crack it open to reveal the egg yoke inside. From my experience, this always
plays will with audiences.
