Iowa fans have started one of college football's heartwarming traditions, waving to a children's hospital overlooking Kinnick Stadium.

The Hawkeyes were on the road Saturday at Michigan State, but Spartans fans kept the tradition going, joining in with the handful of Iowa fans at Spartan Stadium and waving after the end of the first quarter.
