When you click the button, three random nouns will be generated (one abstract, two concrete).
Seen together, what do they make you think about? How does your mind connect them?
I recommend treating this one as a freewriting exercise. Give yourself a time limit and keep writing - notes, ideas, sentences, whatever comes to mind!
When you've written for a length of time, you might want to generate three more nouns and see if they can be woven into your piece of writing.
