How about a language course or class for your grandma? There are many online courses available that provide immersion-style learning. You can purchase the class or find a subscription service that gives her access to multiple courses. Alternatively, you can gift her a language immersion trip to a foreign country where she can take classes and fully immerse herself in the language and culture. Another option could be to create a personalized language immersion kit for her, which includes language-learning materials such as books, audio recordings, and flashcards. This way, she can practice and improve her language skills on her own time.
Or you can get her a star map with an important date you share.
