Alternatively, you could put together a gift basket with some of his favorite documentary films, along with some snacks and cozy blankets for a cozy movie night at home. You could also consider taking him to a documentary film festival or screening in your city, and make a date out of it.
Or you can get him a star map with the date of your first kiss.
