Christian exploits a loophole (and an egghole)
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Christian quickly identifies that there is nothing in the task brief stating when the time starts. He sends Mark out of the lab to write 'Time starts now.' on a piece of paper and, while he is out of the room, makes a small hole in the eggshell and drinks the contents raw. Upon Mark's return to the lab with the 'official' starting instructions, he pretends to very quickly suck the contents of the egg out of its shell. Lasse accepts his resulting time of 5.7 seconds, securing Christian first place in the task.
