    Mystery Rotating

SUMMARY

The discussion centers around the identification of a rotating, S-shaped object observed in a video. Participants agree that the object is likely not a balloon but rather a garbage bag or a similar lightweight object affected by the wind. The consistent rotational movement and stable shape suggest it could be a pair of party balloons tied together, as they can maintain an S-shape while rotating. The consensus emphasizes the influence of wind on the object's behavior.

PREREQUISITES
  • Understanding of aerodynamics and how wind affects lightweight objects
  • Familiarity with the properties of balloons and garbage bags
  • Basic knowledge of object motion and rotation
  • Experience with video analysis techniques to observe movement patterns
NEXT STEPS
  • Research the effects of wind on lightweight objects in motion
  • Explore the physics of rotational motion in various materials
  • Investigate video analysis tools for tracking object movement
  • Learn about the properties and behavior of different types of balloons
USEFUL FOR

This discussion is beneficial for hobbyists in aerodynamics, videographers analyzing motion, and anyone interested in the behavior of lightweight objects in windy conditions.

Somehow it doesn't seem to me to be an S-shaped balloon with it's constant rotational speed. Any idea what this could be?

Why could a balloon not do that?

It's rounded rather nicely for a balloon, holding fairly stable.

Looks like something blowing in the wind.

Agreed. I got the impression of a garbage bag with a few light objects in it. True, the movement was oddly repetitive, but there's really no reason why that's not possible for a garbage bag in the wind.
 
I viewed the vid, and noticed how much the object was affected by the wind.
Balloon or similar for sure. Easy!
And the "S" shape certainly accounts for it's rotation in the wind.
 
Towards the end, the object resolved into a close pair...

My guess, a couple of party balloons tied together...
