What Happens When Vortex Rings (Smoke Rings) Collide
The collision causes about 20 mini-vortices to form around the outer ring. The center also undergoes some surprising transformations. I think we should get together and make one of those giant smoke ring guns out of a metal trashcan. You can shoot them 30-40 yards away.
Class dismissed.
