Simply put, one steps inside this device, makes a wish, and the wish is granted. The Wishamatic represents the first true convergence of psychology and physics (string theory in particular).
In the above example, a young lady has stepped in and wished for a donut. Boom! A conveyor belt appears before her, delivering more than she can possibly handle, let alone eat. A fascinating aspect of this device is that when the materialized wish (in this case donuts) drops to the floor of the device it vaporizes, so our wisher has to catch them first to fully realize her wish....in this candid shot she clearly has. When she leaves the Wishamatic her wish vaporizes which means she has to finish her food and then leave. There are problems if she wishes for Mr. Right. She has to catch him before he hits the floor and decide what to do with him before she leaves. Hmmmm.
You may notice the floor is covered with indestructible Kronon lightbulbs (on which our subject is sitting). The inventor has stated that it is the unique combination of these, the shape of the container and the warmth of the human body which catalyses this remarkable phenomenon. Go figure. The National Organization of Boardwalk Amusement Devices (NOBAD) has shown a keen interest.
