I'm beginning research on how the Earth's Coriolis Effect affects solids suspended in moving liquids. I have run into a challenge that lifehackers may be able to help solve.
I would like to compare two similar liquids—one turning clockwise and the other turning counter clockwise at the same rate. This has presented two challenges to either solve or adequately counteract/compensate.
- How can I stir/spin/swirl two similar liquids in different containers at the same rate in diametrically opposite directions?
- How can I prove/verify that both are turning at the same rate.
I can't figure out how to "mark" a liquid to track its movement. I can't figure out how to affect the liquid (move it) without the interference of some object. For example: I have used magnetic mixers that use encapsulated stir-bars to mix chemicals in my lab but they (and all others I've found) all spin in the same direction sitting on the bench. I found it might be possible to change the direction of the rotation of one of two magnetic mixers; but, that introduces other distractions (the stir bar) that I'd prefer to avoid if possible.
