2:19 the water above the funnel itself is really only pushing down on the funnel, not the displacement piston at the bottom. If you weighed the containers AND the water, the funnel would weigh more because then it takes into account the water pushing down elsewhere.
It's incredible how the thumbnail alone already communicates the phenomenon so well that you understand exactly what's going on without even having watched the video
Years ago when I worked in the industrial water field, this concept was drilled into our heads. It's faster to fill a tank by connecting a hose to the bottom vs. connecting the house to the top of the tank.
Intuitively, some people thought that the bottom was shower because you had to push the water in the whole tank up. But it was actually slower to push the water in the house all the way up the whole time.
In the last setup, the upward force on the container and thus the clamp stand is what we normally would call buoyancy. The container is trying to float above the water, so it becomes lighter.
Many years ago I pursued a physics degree inspired by Veritasium and this channel. A bachelor's, master's, and a PhD later, I'm still loving every piece of content you put out. Thanks for everything Steve!
6:30 Putting a scale under the stand is an excellent way to demonstrate that the fluid above sloped container walls really is supported by the stand. A force decomposition diagram always feels a bit abstract.
The Henson Paradox: the smoother the ad transition, the more impressive and higher the retention but also the higher the resentment at being tricked and the lower the resultant sales.
The clamp stand getting lighter totally broke my brain. And I started imagining what shape the tube would have to be to make the clamp stand float and forgot to pay attention to the rest of the video!
