I’ve seen people blowing smoke rings and dolphinsblowing bubble rings I was wondering if it was a physical possibility to do thesame thing but through soil or sand or whether its too dense.

 

What exactly is a vortex ring? Is it ashock wave of force carrying another substance or is it an actual particle flow

Air bubbles and smoke rings are different substances than the medium, so I think it's clear that it's actual flow rather than a density fluctuation.

You can get fairly coherent ring vortices with a single substance though.

We had one similar to these one Christmas - and you could knock down Greetings cards from at least 20 feet

Fairy coherent rings propagate through the soil.
