In everyday life, code plays a virtual but indispensable role and is used in electronics and networks. The code is an important component in connecting the digital and analog worlds. Just as humans depend on food, technology depends on the code. In this interaction design project, I developed the station "the water dispenser," which is part of the interactive chain reaction. In this station, an endless treadmill, a fan connected to a slide, and a cup dispenser work together. It was run through by an effervescent tablet previously dispensed by the station „Talk to the code." In the end, visitors can drink a cup of water with dissolved effervescent tablets and enjoy the rest of the chain reaction.

After the group discussion, gastronomy became the theme of this project. During the run of all stations, we offered some food, fruits, and drinks for visitors. I was interested in the topic drinks and therefore made a water dispenser in an interactive direction. When the sensor detects a moving effervescent tablet from the last station, it sent a signal to the platform. So actuators would know and started the vertical conveyor belt and a ventilator connected to a slide to move effervescent tablets toward the cup under the water dispenser. Then the machine poured water into the cup, and the whole process would be finished.
