A disabled model has hilariously showed off the challenges he faces in the kitchen in an 'instructional' video.

Footage shows him testing out his prosthetic arm's ability to chop a series of items, some with disastrous consequences. 

Chris Ruden, 28, from Coconut Creek, Florida made light of the at-times difficult cooking tasks, and proved he has a sharp sense of humour.

He has a congenital birth defect which left him with only two fingers on his left hand and a shorter left arm.

In the video, Chris tries his hand at chopping up a clove of garlic, but even getting a hold of it proves an issue.

Unhappy not to get a firm grasp of the vegetable, he brings the prosthetic down on it in a smashing motion.

But then in a moment of comic relief, Chris brings a jar of minced garlic and drops it onto the chopping board.

 'I probably should have picked something easier (like making ice)' Chris said in a caption under the social media video.
