Jukka uses lemon juice and his love for his children to make himself cry
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jukka poured lemon juice in his eye and then started talking about how much he missed his children.
He collects 23 tears in the cup as well as some snot that was not counted towards the total volume.
