What problem does jello create for Julie?

Please provide me with more context! I need more information to understand what problem jello might create for Julie. For example:

* What is Julie doing with the jello? Is she making it, eating it, or is it involved in some other activity?

* What is the setting? Is she at home, at work, or at a party?

* What are Julie's goals or intentions? What is she trying to accomplish?

Once I have more information, I can help you understand what problem the jello might create for her.
