Jakob makes an egg timer
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jakob’s attempt is prefaced with a warning from TV2’s legal department, and with good reason: Jakob decides to use a barrel fire as an egg timer. His entire calculation method seems to be visualising the hypothetical bonfire, and Jakob puts branches and a lot of lighter fluid in the barrel. Mark uses a sparkler to light the bonfire. When lit, the contents of the barrel blast out and land where Mark had been standing when he threw the sparkler in; had he not stepped back after lighting the fire, he would have been hit by flaming branches. Jakob’s cooking time of 5 minutes 42 seconds earns him first place.
