Electric Shows, X-Ray Shows, Scientific Demonstrations, etc.

In the age when the electric light bulb had recently been invented (1879) and the mysterious invisible X-ray had emerged (1876) you could make a show demonstrating the miraculous and weirdness of these new technologies. Thus was born the Electric Show, and much more rare and dangerous, the X-Ray Show. The tradition of course was much older, as showmen introduced the public to such modern inventions as anesthesia, laughing gas, microscopes, adding machines, etc.
