as an idea for the contest, I used a Soviet machine with sparkling water. Improved and updated it, gave a new life in the relatively near future. now the machine is almost completely automatic: the display and the take-off device are powered by electricity, which is generated and used with the help of a solar panel, and payment is made by card or chip (simply by attaching it to the screen), and to eliminate breakdowns, the lever on the case is kept on the left side, the drink is generated from the environment using two super-technological "materializers" inside the output window. The whole body is equipped with illumination, as well as special wings for greater stability in the air. The idea of the availability of drinking in public places, as well as the iconic red color, has been preserved from the Soviet device itself.
