This semester is turning out a little different from what we had hoped, but it has presented the opportunity to try our new things: Torge and his class join me in my kitchen! I log into their online class with two devices, one looking at the tank from the top, the other looking from the […]
Using “One should really play more!” as title of a presentation in a serious scientific colloquium might seem like a bold move, but the gamble payed off: a large, interested audience including everyone from students to professors enthusiastically dropped ice cubes and food dye in our LEGO-driven rotating tanks and passionately discussed their observations. On […]
Yesterday we had four rotating in operation simultaneously, running three different experiments. It’s pretty awesome to be able to bridge spin-up times by just observing what the teams on the neighboring tables are up to, also it’s nice to get a variety of experiments all happening at the same time. Very entertaining and educational indeed! […]
In addition to our four DIYnamics-inspired rotating tanks, we now have a highly professional rotating table with SO MANY options! And also so much unboxing and constructing and trouble-shooting to do before it works. But we finished the first successful test: wanna see some rotating coffee in which milk is added? Then check this out!
Doing experiments like the ones we’ve been doing here is super helpful to let students of ocean and atmosphere sciences find a different way to approach highly theoretical rotating fluid dynamics. But the experiments are pretty and are raising curiosity not only in students, but in most people that see them. To share them with […]
One might ask oneself why we are insisting on rotating tank experiments. In order to establish that rotation isn’t just there to make equations a lot more complicated, but that it actually changes how things behave, we ran two different experiments. Turbulence in rotating and non-rotating system First the probably easiest experiment anyone could imagine: […]
Yesterday Torge and I spent a fun Friday night trying out new rotating tank experiments together with Rolf Käse. Rolf taught the lab course that got me into tank experiments (back in 2004!) and he’s still such a huge inspiration! Rolf brought his tank which features a conical bottom, and this gives so many more […]
The inspiration for Torge’s and my PerLe teaching innovation project was a 2018 article by the DIYnamics team in which “affordable rotating fluid demonstrations for geoscience education” are presented. We were first intrigued, then excited, and since I have always wanted to have a rotating table to play with at home, there was nothing to […]
