In preparation, visitors explore phenomena on interactive experimental fields. For example, they discover how metal balls are made to float or how they generate voltage by laying on their hands. In the control room, they first interactively explore connections to electricity, water and gas before playfully testing their knowledge with others in the control centre.

In order to draw the attention of the visitors to the previously rather closed place, the entrance will be designed with an inviting and at the same time protective entrance area. A blackboard at the door to the transformer room provides information, and the windows facing the Rheinstraße provide initial insights into the subject matter, even in the dark, thanks to slides and projections.
