  The field of quantum information is becoming more known to the general
public. However, effectively demonstrating the concepts underneath quantum
science and technology to the general public can be a challenging job. We
investigate, extend, and greatly expand here "quantum candies" (invented by
Jacobs), a pedagogical model for intuitively describing some basic concepts in
quantum information, including quantum bits, complementarity, the no-cloning
principle, and entanglement. Following Jacob's quantum candies description of
the well-known quantum key distribution protocol BB84, we explicitly
demonstrate additional quantum cryptography protocols and quantum communication
protocols, using generalized quantum candies (including correlated pairs of
qandies). These demonstrations are done in an approachable manner, that can be
explained to high-school students, without using the hard-to-grasp concept of
superpositions and its mathematics. The intuitive model we investigate has a
fascinating overlap with some of the most basic features of quantum theory.
Hence, it can be a valuable tool for science and engineering educators who
would like to help the general public to gain more insights into quantum
science and technology. For the experts, the model we present, due to not
employing quantum superpositions, enables - in some sense - extending far
beyond quantum theory. Most remarkably, "quantum" candies of some unique type
can be defined, such that non-local boxes (of the Popescu-Rohrlich type) as
well as regular (correlated) quantum candies can be generated by a single
`"quantum" candies machine.
