At this point students can go to https://secondfortune.com/ or present them with their own fortune cookie that you either saved up from a year's worth of eating take out Chinese or that you got from a box of fortune cookies, which are available at your local supermarket for around $2 or less for 12 cookies.
This random factor requires the writer to adapt and make a move in a direction that maybe he or she wouldn't have otherwise. Plus, eating a cookie in class is always a blast. What sort of adventures will that fortune go or what impact will that fortune have on the character's current romantic relationship? Worse yet, what if that character opens the cookie and there is a blank fortune? Is that a good omen or a bad one?
Or even put your own sinister fortune in like, "Leave now!" or "meet me at Bennington Park midnight - come alone" using a custom made fortune cookie company: https://www.amazon.com/50-Custom-Fortune-Cookies-Individually/dp/B07JR15BS3
For those of you more extreme than others (and are handy around the kitchen), you can make your own fortune cookies with whatever messages you want inside - https://www.fifteenspatulas.com/fortune-cookies/
If you are using actual cookies or the second fortune, be ready to have a backup fortune, just in case they get a dud for story writing purposes.
