Petra makes a smoothie
Petra initially turns her attention to the bottle, but quickly realises that the lock is a trick, and simply removes it.
It is not shown in the footage of her attempt, but at some point she realises that the bottle has jelly in it, as she sources a long-handled spoon (to help loosen the jelly) from the kitchen, when she fetches the blender.
She removes some of the jelly, then puts Mark to work on shaking the bottle, while she blends the banana up with some oat milk.
She has a few issues with the blender, and has to shake it a few times to move the banana around, but successfully blends the banana, and pours it into the bottle via a funnel.
She does have to scrape some of the remaining banana out of the blender and push it into the bottle, as her mixture is still somewhat chunky.
Petra’s time is not given, but she earns second place.
