The way I believe you meant it, it would be biochemistry. "Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms." While effects of alcohol and constant reiteration of the test arrays is not the primary cutting edge or frontier aspect of it, it counts. ...but only if you are actually recording observations. For instance you could run an array of 500 individual tests while making observations. What effects are alcohol having on you, do they correspond with your hypothesis? How do you negate the observer effect? What factors affect the results? Does eating a lot of greasy food have an impact? Does your level of tiredness have an impact? Are there differences in the effect of the alcohol percentage of beverage tested? I would personally make qualitative observations. "Now I feel happy" -> "now I feel angry" -> "now I feel like crying". Can you gather some kind of a model from all your data? Can you predict hangover, what affects the severity of hangover? Can you identify methods for countering it? I sometimes try to do these things but I keep forgetting where I put my notes and even more often I forget to make notes. Preliminary testing indicates that it is increasingly difficult to record your observations, which is interesting and promising and merits further experimentation.
No no, thus SCIENCE. Not thrust SCIENCE. Thrust SCIENCE requires too much maths and vectors and event horizons to throw in all willy-nilly with the SCIENCE of observing Borf. Anyway, we're derailing. Back to "normal" SCIENCE.
That would be the fascinating realm of biomechanics and hydrostatic pumps! I really love that stuff. You can first start introducing the theory to her from something like Cats' Paws and Catapults by Vogel and after you've covered the theory of hydrostatic pumps it is the optimal moment to get to practice it. It can indeed be practiced, the theory is so self explanatory that it doesn't need to be revisited, instead focus should be on large arrays of tests and iteration to confirm any findings. I find that it is possible to combine the biochemistry's alcohol sampling with this to save time as the two tests do not interfere with each other except perhaps in an enhancing way. That's why I love biochemistry - it has a tendency of enhancing everything. Unless of course if you were talking of organic chemistry that produces a more pyrotechnically pleasing effect.
I have a simple philosophy - full throttle in all aspects of life. Don't just think, overthink everything. Don't just talk, scream. Don't just drive your car, pass everyone no matter what it takes. Now I want to see Tom Cruise living in this kind of community and praising it rather than that "autism in everything" shit, "if there's a way to pour tea for 6 hours in an awkward clothing doing thousands of ritualistic steps, we only ask why not 12 hours and tens of thousands of ritualistic steps". Me, I just remove the top from the kettle and throw the tea at the guests. If they're fast they can scoop it from the air with their mugs.
Did you see the movie The Iceman? I was just told that it's like that when I'm driving.. Another person compared it to this wooden roller coaster. To me, people buy 70k cars but they never use but 20-30% of the car's potential. Also, it's good to know how your car performs at higher speeds in case you were actually chased in earnest. Not to worry, I drive really, really safe. Safe isn't mutually exclusive with actually speeding up to and slightly beyond the allowed speed, reaching that speed today and not tomorrow. Some folks, they slow down when the light is green.
