Gotta agree with Carl, up to a point.
The trick doesn't so much end as stop!
It's like the linking rings: You link one, then two -- okay, the audience accepts that; why continue and link all the rings?
In the egg bag, the egg vanishes and reappears; okay, once is enough -- why continue until the audience is begging for mercy?
Now, the important part has been overlooked (and I've raised this issue several times before in various places):
Who carries eggs in a bag?
There is absolutely NO justification for using eggs.
In fact, it's downright silly!
For an alternative, check out this month's Linking Ring magazine for my Showtime column in which I have a routine called the Golf Bag; it's an egg bag (a) using golf balls instead of eggs, and for a reason; and (b) it has a climax, rather than just petering out.
(My routine uses the Don Alan handling from Bruce Elliott's brilliant book, Classic Secrets of Magic -- unfortunately, no longer in print.)
Sorry, but I've seen many top "names" do the egg bag and never once did I see it done well.
