Write a story
There are many ways to write a story together. Over the course of a day or week, construct a short story with one or more people, one sentence (or paragraph) at a time.
You can use email to send it back and forth, work in a collaborative space like a Google Doc, or talk it out in real time using the phone, text or video chat.
Since you won't be in the same space as everyone, you won't be able to throw a ball, but as long as the story teller keeps changing, this is a great way to create a new story with 2 or more people.
