Zoom physics 7b - life at a small scale


I left out flying insects who have to use a snap to fly.  Some insects smash their wings at the top.  Others go super-fast.

okay!
so that was interesting!

the vortex in your drain in the northern hemisphere spins in one direction
but in the south it's opposite
so do all vortex, in the southern hemisphere also have an opposite spin.
(paddling, swimming and the like)
or is that directed by the swimmer or paddler?

this is kind of fun and different!
It's a different way of thinking about ordinary things
