That is a link to a Geogebra animation of a machine pumping up a balloon full of air.

I had, on my drive, dismissed those kinds of animations — precisely the “filling up” animation.

I am NOT going there.  Yet. I’ve been disillusioned often enough by geogebra not to interrupt even after I see “everything automatically animates.”

I do want to try to make my “drag and drop” accessible to students w/ motor issues.  Supposedly the arrow keys will work, too but I fear it will be like control z not *really* undoing things.  I’m also thinking about what colors will work best (and how easy it would be to have different versions).
