The Myth of the Swirling Toilet Bowl Water
R. Philip Bouchard

Fantastic piece!

Since we’re so used to thinking of the ground as unmoving, the way I often explain the Coriolis Effect is to imagine that there’s a strong wind blowing from west to east. You (in the northern hemisphere) throw a ping pong ball due north, and it will bend in a curve towards the east. That’s a lot easier to imagine.

Likewise, just reverse the position of the “wind” for someone in Australia.

Other metaphors I’ve heard include imagining being a miniature person standing on a 45 LP “record”, but that only works for people old enough to remember them :P
