Symmetrical Stacking is a unique form of psychokinetic activity that involves the precise vertical stacking of books.


Primary Canon

While investigating a sighting of the Library ghost in the New York City Public Library, Peter Venkman, Ray Stantz, and Egon Spengler observed symmetrical stacking. Peter was skeptical it was paranormal in nature. Ray cited the Philadelphia Mass Turbulence of 1947 event while Egon took readings with the P.K.E. Meter.

Tobin's Summary

In certain ares of high psychokinetic activity I've seen peculiar things happen to small objects, especially flat ones. In addition to the almost commonplace levitation and hurling about objects will occasionally end up in perfectly symmetrical stacks, ranging anywhere from a few to dozens of feet in height. I've measured several of these stacks over the course of my studies and they all exhibit perfect mathematical symmetry beyond the capabilities of normal human beings.

Egon's Notes:

I've had the privilege of seeing a few of these stacks firsthand. It's fascinating how rapidly these stacks can be assembled, almost falling haphazardly into place but still retaining their amazing symmetry. Had Tobin been around for a few more decades, he would have seen the Philadelphia Mass Turbulence of 1947, one of the most impressive instances of this phenomenon to date.

Ray's Tips:

Don't do what Venkman did and try to play Jenga with them, OK?

Supplemental Data

The art page can be found in the NYC Public Library, during the "Get Her!" section. It is hidden in a microfiche reader in the room just before the sorting room; lots of stacked books are nearby.

Dimension 50-S

In Dimension 50-S, Symmetrical Stacking was observed upon entering the Mrs. Roger's House construct. Samuel Hazer remembered the story Ray told the junior team.
