Wundt was unconvinced by what he saw – but a number of his esteemed colleagues, including world-renowned physicist Johann Zöllner, believed that the events they had witnessed called for a complete revision of the fundamental laws of physics – a revision that could accommodate immortal fourth-dimensional spirit people.

The resulting debate was not itself immortalised in any mainstream psychology textbooks, but, arguably, it played a fundamental role in the subsequent emergence of Experimental Psychology as a formal scientific discipline. Magician and experimental psychologist Dr Matt Tompkins mixes storytelling and magical scientific demonstrations to explore how scientists, past and present, have approached the study of illusion.
