Disclaimer: I had previous experience with pretty much all of the parts involved, just not in this combination - so I consider it less of a dare and more of a research project
Did it anyway because I like it messy.
Background:
Made a point of sticking to the plan as close as possible, but I did not want to mess up my footwear, so I walked on my toes instead.
I have excellent body control so it probably would not have made a difference, especially with my experience with slippery messes.
I choose a pair of black fine-mesh stockings and red string as my outfit. In my head snow white and little red riding hood are the same person, so it seemed befitting.
For the mess I am using one bottle of native olive oil, 750 mL and two 2kg bags of soft wheat flour.
Laid out an extra towel, soap, all the clothing and parts in a box and went to the shower. I had opened both bags of flour beforehand.
The oil-up:
Started out with the oil as per usual form the neck down, smearing it on sloppily and making sure my shower walls get a piece of the action too. Rubbing against those walls to make sure I cover every part of my surface. Rubbing under the armpits, interlocking fingers, that sort of thing. Bending down and squatting a little to cover my legs, butt, crack, genitals, feet, again rubbing all over. A substantial amount dripped on the floor, for me to step into to get good coverage under my feet as well, or should I say toes. Rubbed between them with my fingers before finally doing my head. But before then I decided to get some colorful lights all around to fully appreciate my new shininess. The head was quickly done with both hands filled with a pool of oil and rubbing all over before pouring a generous amount of it right on top of my head, making its way down my neck, my back, over my shoulders, down my chest - making me feel like a stack of pancakes being syruped up.
I do not particularly like the scent of olive oil so that put a bit of a more sinister touch to the scene, although the primary sensation in my nostrils was overtaken by a previous research project.
I enjoyed the sensation, being slippery, shiny and feeling a little warm, decided to admire this state for some time, and roll around in the pool of oil that had accumulated on the shower floor, then proceeded to walk around a little to fully appreciate the state.
The dress-up:
After I got that out of my system it was time to go back to the plan, I retrieved my clothing and started putting on a stocking and oiling it up.
I discovered the fine-net stockings absorbed a lot of oil and did not form a shiny film on the outside no matter how much I poured on it. They remained quite rough and grippy, eliminating the challenge of slippery feet altogether. I also was worried they would not take on any flour so I decided to skip them entirely. Put on the string, which was made of a much finer fabric, having no trouble getting oiled up. Tucked on it a little to enjoy the sensation around my private bits. For good measure I poured some more oil over my chest, letting it pour down.
Making it snow:
I did not expect this to work out like in the comics, turning albedo from 0 to 100 with a single pour, but decided to do it exactly that way anyway. Retrieved the first bag of flour and promptly emptied it over my head, forming a sizeable pile on my head and covering parts of my body before accumulating on the floor. Not surprising but fun nonetheless! Proceeded to shake violently, making it snow in my shower. Again, after that little tantrum I squatted down. Scooped up piles of flour and patted it on me. I did hope for more, but as it turns out this flour binds oil more readily than I had anticipated, only covering me with a thin layer at best. The entire mess was barely noticeable haptically, and for the most part I felt clean, even though being covered in oil/flour all over. I decided to roll in the pool of flour to ensure I had not missed a spot. No difference.
Dumbfounded, I tried slapping various parts of my body to see if that felt different, which released little clouds of flour in the process, at least it is something.
Conclusion:
Flour on an oiled body may seem like a fun idea, but I do not see it working for me in this way. In fact I enjoyed the flour more in the cleanup, forming little beads of goo and feeling all sticky. Olive oil has shown to leave only a thin coating, which is spread even thinner focusing body weight on toes, not reducing friction as much as anticipated. Together with the smell I think I stay with sunflower oil.
Future work:
Better results may be achieved with different types of flour. Coarser types potentially provide a higher albedo as fewer particles need to stick.
The application method could be improved as well - like dispersing flour through a fan, producing a finer dispersion pattern and preventing clumps of flour droping off removing oil.
