The Youtube algorithm fed me that video a couple of weeks ago. Very interesting.
What's the deal with liquids in unstable flat-sided bottles?
Are they designed to topple over and spill?
In the TV rental trade in the '70s we used gallons of Joynes Waxless Polish, which came in a glass flat medicine style bottle. I think most of it was accidentally used to polish the bench tops when the bottle got knocked over.
