# Tunnel Paint: Optical Illusion Research

## Abstract

ACME Tunnel Paint creates a photorealistic tunnel entrance when applied to any flat rock surface. When viewed from the road, the painted tunnel is indistinguishable from a real tunnel.

## Application Method

1. Select a flat rock face adjacent to a road
2. Apply ACME Tunnel Paint in the shape of a tunnel entrance
3. Add perspective lines for depth
4. Optional: paint a road leading into the tunnel
5. Wait for target to drive/run into rock face

## Observed Results

In 100% of trials (n=9), the target enters the painted tunnel as if it were real. The target's feet produce audible footsteps that echo, and headlights illuminate the painted interior. The target emerges from a previously nonexistent exit on the other side of the rock formation.

When the operator attempts to enter the same painted tunnel, it behaves as expected: flat rock. The operator's face compresses to approximately 1 inch in depth upon impact.

## Theoretical Framework

We have no theoretical framework for this. Three physicists have reviewed the data. One quit. One is on sabbatical. One submitted a paper titled "On the Selective Permeability of Painted Surfaces" which was rejected by every journal.

## Recommendation

Discontinue tunnel paint research. The paint works, but it appears to have preferences about who can use it, and we are not on the list.
