A TRUE ARCHIVE MYSTERY · ABOUT 12 MIN
THE CABINET TEST
Two restrained performers enter a dark cabinet with musical instruments. Sounds follow, objects move and a coat changes position while the bindings appear intact. Decide what the restraints actually controlled.
Examine eight exhibits, choose the explanation that accounts for all of them, then select the three strongest independent controls.

Readable evidence fallback
The interactive controls require JavaScript. The complete evidence remains readable:
- The restrained performers sat with instruments in a cabinet hidden from view.
- A favorable periodical called earlier tests thorough.
- A favorable account reported seals left intact.
- Visible intactness, pain and mechanically blocked movement are distinct.
- Barnum proposed ways ordinary tying could leave slack.
- Ferguson alleged injury; refusing a painful test is not an admission.
- The audience-selected Liverpool restraint was removed before continuation without that committee.
- Manchester imitators reproduced a similar effect through temporary release.
Possible explanations: an external agency; misread ordinary events; or temporary release.
