Judging by the model in the video, Polaris should be visible from the southern "hemisphere". Since you're a "globetrotter" (tongue in cheek), next time you're in Australia, South Africa, or Brazil, look due north, try to find Polaris. Tell us what you find.
One of many indisputable jugular shots to the spinning globe/"solar system" model: Every planet traces a perfect symmetrical pattern around Polaris in our sky.
This would not happen if we were all orbiting around the sun at different unfathomable spinning speeds and tilts.
Star trails prove without a shadow of a doubt: The North Star is a static luminary above us, and all other stars, planets, and constellations revolve around US. Earth is stationary.

Also while at it, Flush the toilet also and see which way it spins.. unless one side of the flat earth has it different?
Though the Coriolis effect is overrated. At least when it comes to drains and such.
Very good question - why can't you see the North Star/Polaris from the far-southern countries?
