Suspense is dynamic. Suspense is forward movement. What comes next? How do I move readers to turn the page, visitors to take the next step? Not by forcing them, but by making the decision easier.
In films, suspense is often produced through action. What happens next? In exhibitions, this can also work – for example, by placing a character at the center: What did they do then? However, exhibitions are more cumbersome than films, more static.
That is why it can be sensible to detach oneself from concrete screenwriting techniques and instead ask – and hey, everything is allowed to be thought: How do I motivate visitors to take the next step? Literally: the next tiptoeing / stomping / hopping step.
For example, by stringing together things that are interesting. Suspense is forward movement. Interest means concentrating on what I see, read, or hear right here and right now. Delving in, engaging. Studying the display case closely, each individual object.
Interesting! What comes next?
