But when inspectors from the city examined it, they realized that Redheffer had simply hidden the power source. To expose Redheffer, they commissioned a local engineer to build a similar machine, and when they showed this to Redheffer he fled the city.

But on the day of its publication, Sokal revealed that it was actually intended as a parody, a fact which the editorial board of Social Text had failed to recognize.
