Thornton marched into the third round of the Macron Scottish Junior Cup following this terrific performance which saw them record their highest ever scoreline in the country's premier competition.
Playing into a very strong wind, Max Coleman opened the scoring in the 21st minute when, following a powerful run, he shot low into the net from 22 yards. Garry Thomson doubled the Hibs' lead with a thunderbolt free-kick in the 32nd minute and when Shaun Keatings netted the third on the stroke of half-time following good work by Coleman and Thomson it was almost game, set and match.
Any hopes the visitors might have had about mounting a second-half comeback were dashed less than sixty seconds after the re-start. Keatings' long range effort smashed off the underside of the crossbar and Samuel Anderson, under pressure from Thomson, watched in anguish as his attempted clearance ended up in his own net.
Two minutes after that, Thomson claimed his second with a screamer from the angle and although Daniel McNab came close to making it six with a free-kick that struck the crossbar in the 64th minute it wasn't until the 74th minute that the Hibs found the net again when Stuart Drummond netted from the spot after Scott Orrock had been brought down.
The men from the North scored an 84th minute consolation goal from the penalty spot with their top scorer, David Baillie, ramming the ball home following Drummond's clumsy challenge on Adam Davidson.
Scott Orrock had the final word when he headed the seventh, his first goal in a Thornton jersey.
