In [Commun. Anal. Geom. 7, 551--583 (1999; Zbl 0940.57025)], \textit{K. Miyazaki} and \textit{K. Motegi} studied Seifert fibered surgeries on hyperbolic knots from the viewpoint of ``locating Seifert fibers'', and made use of Jeff Week's computer program SnapPea (freely available from http://humber.northnet.org/weeks/SnapPea.html) in order to investigate a relationship between closed geodesics in hyperbolic knot complements and Seifert fibers after Seifert fibered surgeries on them. In the present paper, the author explains how they obtained their experimental results with SnapPea. He demonstrates how SnapPea may be used in order to perform a lot of experiments concerning knot complements and surgery (for example: how to check whether a given knot is hyperbolic or whether a Dehn surgered manifold is hyperbolic, or how to find curves in knot complements which become fibers after Seifert fibered surgery\dots). The paper also contains some proposed questions, inspired by the computer experiments.
