We experimentally tested the rubber hand illusion over a mirror where the rubber hand was seen in a mirror unlike typical experiments. The study was composed of three experiments. In the first experiment, we reconfirmed that the illusion was experienced when the participants stared the fake hand in a mirror. In the second experiment, the illusion was reported even with an incongruency between the actual and fake hand postures. Finally, in the third test, a smoke mirror was judged to be more effective than a clear one. These findings suggest that an obscure fake hand image in a mirror leads to a condition where the rubber hand illusion is readily experienced.
