Last Thursday, Torge & I invited his “atmosphere & ocean dynamics class” to a virtual excursion into my kitchen — to do some cool experiments. As you know, I have…
Several of my friends were planning on teaching with DIYnamics rotating tables right now. Unfortunately, that’s currently impossible. Fortunately, though, I have one at home and enjoy playing with it enough…
I was super keen on trying the Taylor column experiment, but maybe I expected things to look too much like my sketch below, or my technique isn’t quite perfect yet,…
For both of my tank experiment projects, in Bergen and in Kiel, we want to develop a Taylor column demonstration. So here are my notes on the setup we are…
One of the first exercises Torge and I plan on doing with the students in our “dry theory to juicy reality” project is to bring a water-filled tank to solid body…
With all the rotating tank experiments I’ve been showing lately, one thing that comes up over and over again is the issue of solid body rotation. On our DIYnamics-inspired turntable for…
Ekman spirals — current profiles that rotate their direction over depth, caused by friction and Coriolis force — are really neat to observe in a rotating tank. I just found…
Inspired by the article “Affordable Rotating Fluid Demonstrations for Geoscience Education: the DIYnamics Project” by the Hill et al. (2018), Joke, Torge and I have been wanting to build an affordable…
Confusing students even more by discussing how momentum is being transferred from the tank to the water. As you remember, we are preparing for the Ekman experiment and need to…
Spinning up a tank until all water particles move with the same angular velocity. Before running the Ekman spiral experiment, the tank needs to be spun up to solid body…
