Now, if you instead constrain the water to like between two walls, such as by taking a thermos and cutting it in half... You still have a blender. H Mal volu,e of air present will mix vigorously, which might be desirable to provide oxygen.
If you make an o-ring and depress it into the cylinder while removing air, then you will be a happy camper.
Alternatively, you can take a bucket of 50cm and calculated the "bubble" of water you will form by spinning it, noting the critters at the walls will be subject to extreme agitation from turbulent flow, from eddies forming spinning counter to rotation of the walls. You'll also have air bubbles all over the place exploding your isopods on contact. Maybe.
If you calculate how to do things like you want, you get a typical chemistry centrifuge.
This is also why I don't think fish or birds would survive in a mckendre cylinder.
Where are you going to get a half-meter glass cylinder?
