SUMMARY

Ice circles are natural phenomena resulting from a unique combination of freezing ice and river eddies. They can be replicated in laboratory conditions, demonstrating their emergent and self-organizing properties. The formation process involves chunks of ice being caught in river eddies, where they rotate and freeze, creating a circular shape. This phenomenon is not a hoax or related to UFOs, but rather a fascinating example of physics in nature.

PREREQUISITES
  • Understanding of fluid dynamics and river eddies
  • Knowledge of ice formation processes
  • Familiarity with laboratory experimentation techniques
  • Basic principles of emergent phenomena in physics
NEXT STEPS
  • Research the physics of fluid dynamics and its applications in natural phenomena
  • Explore laboratory experiments that replicate ice circle formation
  • Study the role of temperature in ice formation and its effects on river ecosystems
  • Investigate other emergent phenomena in nature and their scientific explanations
USEFUL FOR

Scientists, environmental researchers, educators, and anyone interested in natural phenomena and the physics behind them will benefit from this discussion.

How would you let that imaginary metal ring float in the first place?

some more here.

I wonder where you buy these metal rings

Obviously, google.nl is a much superior search engine for solving such problems:

My ex roommate swore by natural ice.

Btw, what are we arguing here?

hic!

You guys ever heard of these things?

I had no idea.

(No they're not hoaxes; they're completely natural.)

Oh. I see. They're supposed to be completely natural.

hmmm...

Why are there ice shavings all around the circle then, as if someone had gone out and cut through the ice to make a circle, so it would rotate due to the difference in stream velocity?

I want to see a natural one.

hmmm...

I think I'll run off and get some pictures from 25+ years back and post them.

Natural ice barstools and tables.

you think I'm kidding, don't you. Shouldn't take more than 30 minutes to find and post them.

Please don't ban me until then.

You've shot your skepticism from the hip.

The shavings accumulate as the ice sheet grinds off the protrusions. This was quite apparent in the lab experiment.

Again. So many peoople are so dying to claim 'hoax', when in fact, the natural explanation works perfectly well. Are you skeptics next going to turns your sights on the implausibility of regularity in mineral crystals and snowflakes? :rolleyes:

btw, welcome back omcheeto. Haven't seen you around these parts in ages.

Like Integral, I can imagine an ice circle forming, just not the ones shown so far.

And I'm afraid I missed the lab experiment.

In the image of the most infamous ice circle, there is are too many circular patterns way too far away from the edge, indicating that the perp did in fact walk around the inside of the perimeter whilst cutting the hole in the ice.

Classic man made crop circle technique.

Sooooo, we have a perfectly acceptable natural explanation that you're not refuting, but you feel an additional explanation can't hurt? The more the merrier?

Let me introduce you to a dude named Occam...
