Cardiff’s mid season resurgence continued as they comfortably won the capital clash in the Celtic League, scoring a half century of points along the way.
Meadowbank was rocked from the opening whistle by a Blue Army hell-bent on victory in order to keep in touch with The Ospreys in the race for a Heineken Cup spot next season.
Cardiff ran in seven tries, with Donovan van Vuuren, Nick Walne, Matt Allen, Jonny Vaughton, Matt Cockbain, Rob Appleyard and Nick Macleod crossing. Nick Robinson kicked a penalty and added six conversions, as the Blues registed their biggest score of the seaosn
The writing was on the wall after just sixty seconds when a marauding pack caught Edinburgh offside and Nick Robinson stepped up to score a penalty goal from 35m
Despite the elements, the Welshmen looked the more potent unit but Craig Joiner’s massive clearance kick to touch inside enemy territory relieved the home pressure.
Edinburgh stole the line-out, giving Ally Warnock the time and space to slot a fine opportunist drop goal to level the contest.
Cardiff responded in positive fashion to force the Gunners into a period of defence – and it was a slip by Warnock which presented them with the opening touchdown.
After the outside half had knocked on virtually under his own crossbar, Andrew Moore delivered the scoring pass to van Vuuren.
Robinson slotted the conversion from an awkward angle – but minutes later he shook his head in dismay as a simple penalty crashed back off the post.
The Welshmen kept up the momentum and deservedly stretched their advantage with a fine finish by Nick Walne after more strong work by van Vuuren.
Edinburgh countered through Tom Philip, whose battling run out of defence paved the way for Conan Sharman to mark his comeback with a long-range effort, goaled by Warnock.
But with just second of the half left, Australian World Cup ace Matt Cockbain celebrated his Cardiff debut with their third touchdown, converted by Robinson.
The visitors upped the tempo even further after the restart and snuffed out the challenge of the Gunners with a burst of two more tries.
Rob Appleyard’s counter made sure of the bonus point – then veteran centre Allen ploughed through for number five.
The one-way traffic continued as Vaughton and MacLeod joined in the rout. Robinson kept up his superb kicking sequence by landing all four conversions.
