Annika raises Mark's heart rate
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Annika decides to raise Mark’s heart rate by stressing him out. She attempts to accomplish this mostly by making Mark close his eyes while she pops balloons – her reasoning seeming to be that the anticipation of not knowing when the balloon will pop will stress him out; however, the pops seem to distress Annika more than Mark. She then moves on to throwing pillows at Mark’s face and yelling stressful things at him through a megaphone (such as a dire warning that is an impending financial crisis that will demolish the worth of Mark’s newly-purchased house). Finally, she declares Mark to be a prisoner of war and places a basked over his head while popping more balloons near his face. Annika manages to raise Mark’s heart rate by 24 beats; she earns fourth place.
