The length and steepness of the climb builds anticipation.
The length and steepness of the drop creates fear.
Long gaps between ups and downs create curiosity.
A rollercoaster is simply a device that controls our emotions. It doesn’t talk to us. It doesn’t convince us. It highjacks our feelings through physical sensations.
Somehow, through something that compresses, extends, and cycles all sorts of feelings through us, we come out feeling happy and cleansed. If you want to make a pitch, think about the emotions you want to bring out in someone, you can take them on your rollercoaster.
