Polygraph

New 3/2026Deutsches Spionagemuseum - The Truth Chamber Signet

Are you ready for your moment of truth?

Two rooms. Two lie detectors. A heartbeat – and the all-important question: truth or lie? At the German Spy Museum, “The Truth Chamber” offers an interactive, high-tension experience centred on the myth of the lie detector. Here, you’ll face not only tricky questions – but your own pulse.

Even in the waiting area, you’ll learn fascinating facts about the history of the polygraph and its use by intelligence services worldwide. But then things get serious: as soon as you take your seat in one of the two test rooms, your personal truth experiment begins.

Your heartbeat is measured and becomes part of the performance.
Subdued lighting. Dynamic projections. A specially composed soundscape that reacts to every change in your heart rate.

Your pulse becomes audible. Palpable. Impossible to ignore.

You answer the questions. The tension rises with every passing second. Every beat changes the room. Until the moment arrives when everything is decided: truth or lie? What makes it special: two rooms that can be used simultaneously ensure double the thrill and no long waiting times. Whilst people are already trembling next door, your countdown begins.
