Queen's Park ran riot against an understrength East Stirlingshire in their Challenge Cup clash at Firs Park.
The visitors, who could have scored even more, went ahead on 24 minutes when Paul Ronald headed home a corner.
A minute later, Ronald's cross was turned into his own net by Shire defender Scott Livingstone.
Richard Bowers fired in a shot from 20 yards before an angled strike from Paul Paton and Shaun Molloy completed the rout with a thunderbolt drive.
