This is the kind of thing where even if kids don’t seem to really be interested in it, even if they don’t seem impressed, it’s such an incredibly rare and unique event (close enough to home) that they will always remember it. Maybe not to the point of thinking about it every week, but in the sense that every mention of solar eclipses, at the very least, will remind them of this one moment in totality with you. You can plant some seeds for interests without knowing what will take root while still knowing the seed stays there.
