Check for a ceramic studio in your area and see what it takes to have a group get together. This is something that can be fun for any age, and for any reason.
If there is no ceramic studio in your area you can always go to the near by craft store and pick up your own supplies. No room at your house, then why not go to the park - just make sure to bring lots of newspaper to put down on the tables.
