"Almost Impromptu Solid Ghost" by Jim Ryan, in which a ghost is captured in an ungimmicked handkerchief was published in The Magic Menu, Jim Sisti, (editor) Issue 43 September/October 1997, Jim Ryan Issue. The concept is easy to duplicate, but as Pete McCabe says, it is not useful to all situations and routines.
Here are some more published routines:
GREATER MAGIC DVD #24 - BURGER'S SPIRIT MAGIC
Buffaloe, Jim: Buffaloe'd - The Magic of Jim Buffaloe 1998; P. 182 The Capricious Ghost: a small ghost performs various feats (uses Glorpy, Cybernetics, a reel, etc.)
Ganson, Lewis: The Art of Close Up Magic Volume 1 (c)1996 L&L Publishing; P168. A ghost appears under a handkerchief lying on a table. A variation of Dik Van Brummer's Solid Ghost, or a more modern version known as "Glorpy". Includes an additional tip from Alan Alan.
Glorpy was created by Madblood Creations (Bill Madden and Bernie Trueblood) circa 1960. It was declared the "Trick of the Millenium" by Genii, the conjurer's magazine, so I figured back issues of Genii would be a treasure trove of innovative Glorpy routines.
From Charlie Miller's Magicana, Genii Volume 37 (1973) Page 424: HAROLD A GOOD CLOSING EFFECT
EFFECT The Magician shows a pen and a deck of cards and explains that his invisible assistant, Harold, will help out in the next trick by invisibly marking any card called for with its position in the deck. I'm sure you can guess what happens.
That's it. Thanks to good old Charlie Miller, Genii has one Glorpy routine from that era. The rest consist of commercial routines published in books:
Hank Moorehouse: "Glorpy Surprise" circa 1975
"Just Another Magician? Hell No! - The Magic of Don Hudson (for adults)" circa 1980, contains a "Glorpy without the gimmick"
Carl Dreher's "Professional Close-up Studio - Volume 1" (circa 1981) which describes how to turn a Glorpy ghost into a wine glass then
into a full-size bottle of wine.
Perhaps we'd have more luck brainstorming NEW and ORIGINAL routines for kids using Glorpy.
I'll start. Since Glorpy looks a little like a ball when it first appears, it might be combined with an appearance of solid rubber balls or billiard balls, or even sponge balls. The balls appear under the Glorpy one by one, vanish, reappear under the Glorpy, and then when placed under the Glorpy one final time, they all vanish. This might be a good use for the ungimmicked Glorpy.
