Minor spoiler for the Opening Gambit: In the opening gambit*, MacGyver uses the map (the procuring of which was his primary objective) to cover or seal a hole in the balloon--he taped it to the balloon with duct tape.
The obvious question is: why didn't he just use duct tape to seal the hole? He could have made a 6in x 6in patch with the tape, and used that instead. It would have been more effective as a seal and would certainly have protected the all-important map. (But then, it would have limited the number of ways he used the map to escape. We saw a total of four way to this point, and the balloon was the fifth way he used the map. But it really made no sense to do what he did.
BTW, I really enjoyed the Opening Gambit of these first-season episodes. I think one of the mistakes this show made after the first season or so was to drop it.
