1-25b-קידושין-כה-ב-משיכה הגבהה ומסירה

What is the הבנה  in the קנין משיכה? Are you קונה  because you do an action that shows ownership since this is an action usually done by owners (similar to the קנין חזקה) or is משיכה  an action of bringing the object into your domain (similar to קנין חצר)? Is קנין הגבהה  and קנין מסירה similar, related, and maybe even learned from קנין משיכה , or are they each distinct forms of קנינים  unrelated to each other? Enjoy!!   7 minutes E.C. question - Can elephants jump?  (Hint- see תוספות)
