Edible Light Pipe Made of Candy

In recent years, there have been widespread attempts to enhance and extend the sense of food using light and images. As one of such attempts, a method to create transparent optical elements using foods such as candy and agar has been proposed. In this study, an edible light pipe made of candy is proposed as a new edible optical element to decorate foods by light. We report the results of basic evaluation of a prototype light pipe made of candy. We also propose a method of supplying light to the light pipe from a remote location using a laser.
