Knowing and seeing how it works takes away a lot of the magic, but imagine finding a completely featureless whirring metal cube... that then jumps up onto an edge, then onto a corner, and starts spinning. And is capable of doing this on any random surface.

I bet that would puzzle even most people who consider themselves familiar with physics and when the cube suddenly jumps back from a corner onto a face, clearly showing that the jumping isn't just some hidden mechanism that extends, make some seriously consider the possibility of magic.
