Space isn't really a vacuum. There's plenty of stuff drifting around, just that most of it isn't all that helpful to our wellbeing.

Space isn't really a vacuum
Wait what?
Space is a vacuum.
Could argue it's not a perfect vacuum. We haven't created a perfect vacuum on Earth but we have come close.
If I have a container and remove all the air inside. I have created a vacuum. Not a perfect one, but a simple vacuum.
If I add rocks to the container. The rocks are now in a vacuum.
Just like space. Space is a vacuum and there is "rocks" in it.

This hit especially well given that our kitties are afraid of the handheld vac. Interestingly, we just got a robo-vac and they aren't afraid of it. They watch it and one followed it to observe. I guess they can go to space if space is a robot.
