Narrative:

While on a flight with a private pilot candidate, we were practicing cross country diversions. After passing arthur dunn airport (X21) we diverted to sanford (sfb) at 2500 ft. As I was extremely busy helping my student, we accidentally penetrated orlando international class B airspace over the lake that is approximately 5-10 mi northeast of ovido intersection. We were only in class B airspace for no longer than 3 mins and upon realizing (as we reached the western shore of the aforementioned lake), immediately initiated a descent to 1500 ft, clear of class B, and returned to an easterly heading of 090 degrees, at which time proceeded back to our home base of melbourne (mlb).
