A viral video shows a dad bouncing on bouncy bog ground that’s ‘like walking on a Black Forest gateau’.

Gary McHugh and his dad Cathal were walking the Dearg Line, near Barnes Mór in County Donegal, Ireland, when they found themselves next to the ground.

Interesting footage shows Cathal bounding across the wobbly land as if he was stepping on a water bed.

Gary said: “The whole thing has the consistency of walking on Black Forest gateau.

“It’s just like walking on a sponge cake, that feels a bit more interwoven and firm.

“Even though it looks like it would suck you into the ground, it is pretty solid and structured.

“It's made up of plant mater that has degraded over thousands of years, you’d need a shovel to cut into it.

“The bog is about two metres deep. It has been an area where the local council rents out plots for cutting turf.”
