Ghost Glass II, Impromptu Ghost Glass lets you create any image.
This is a special liquid used to simulate the ghost glass effect on any glass surface.
Just paint an image with this invisible fluid, and when you want the image to appear, simply breathe on the glass.
Can be applied to drinking glasses, reading glasses, glass counter tops, mirrors, just about any glass surface.
You can cause spirit writing to appear almost anywhere at any time.

IDEA: If you apply this chemical to a drinking glass, the addition of ice will cause the image to appear.
