Hydrodynamic analogs have been developed that can recreate various aspects of quantum mechanical systems, including single-particle interference through a double-slit.  A silicone oil droplet, bouncing along the surface of a liquid, self-propels via resonant interactions with its own wave field. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet’s interaction with its own ripples, which form what is known as a pilot wave , causes it to exhibit behaviors previously thought to be peculiar to elementary particles — including behaviors customarily taken as evidence that elementary particles are spread through space like waves, without any specific location, until they are measured.  
However, restaurant booth space requirements are largely determined by the width of the table top. For example, if your restaurant’s menu and food service style ( like pizza, Asian or Mexican food) require more than a standard 30″ wide table top you may need to plan for more booth opening space. Conversely, if yours is a fast food establishment, coffee shop or an employee breakroom a narrower table top width (like 24″) will result in a space savings of 6″ per booth opening compared to using a 30″ wide top.
