Of slime and childish curiosity

March 26, 2011

In which Dr Aust ponders slime. And scientific tendencies.


Reproduced from the wonderful xkcd.com, the comic strip that regularly captures the spirit and the reality of science

Last weekend the Aust entourage, including Junior Aust (aged six-and-a bit-well-nearly-seven-in-a-few-months) visited this event at one of the nearby museums, run by the people from Manchester University’s Life Sciences Faculty.

In the event you could, as it says, “Come on a tour of the human body” and learn “how the heart works and how your lungs help you breathe”, among other things.

Junior Aust was fairly unimpressed by the nice chaps with their two-electrode ECG trace, even when I told her it was one of the things dad gets his students to measure on each other. I think the ECG wasn’t participatory enough for her, as they weren’t allowed to wire up members of the public (a shame, really, but understandable).

I DID manage to persuade her to blow into the spirometer and have her Forced Vital Capacity measured – another of those things you can find me getting students to do in their lab classes. I also measured myself for comparison, though I’d already done my annual Hypochondrial Full-service Multi-parameter Respiratory Function Self-assessment while I was running the student classes earlier this Semester.

She was a bit more impressed with the video of the view of the inside of your airways during a bronchoscopy (not done live, before you ask!), which I was able to tell her was the kind of thing mummy used to do to patients.

But the thing that REALLY made a deep and lasting impression on Junior Aust was the “make your own mucus-alike slime” stand. Kitted out in disposable plastic pathologist-style apron and dashing purple nitrile gloves, she was helped to concoct some truly disgusting-looking greeny-yellow slime out of acrylic glue, water and food colouring. I reassured her that the yellow colour was just enough to made it look properly yellow phlegm-like and grungey, and she was given some of her confection (tied up in another nitrile glove, no plastic bags left) to take home.

Now, we assumed she would lose interest in the stuff quickly enough, but this turned out not to be the case. For the rest of the day we were repeatedly called into action to stop her turning the slime out over the table, or the chairs, or the floor. Despite our best efforts, small chunks of it made their way onto her and her brother’s clothes, and onto the furniture. Yum.

But then we made a truly catastrophic error.

** Warning – you may find the next bit slightly disgusting. **

In a moment of attempting to out-gross Jurior Aust, The Boss (Mrs Dr Aust) remarked “That slime” (which was now semi-congealed) “looks exactly like what was in Junior Two’s nappies when he was ill the other week*”

Oh dear.

Big mistake.

Big, biiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiig Mistake.

Huge.

For, thoughout the week since this conversation, we have been regaled daily (or indeed several times each day), by one or both children, with the useful information, faithfully and exactly repeated, of just exactly what Jr Aust’s slime resembles. Typically combined with a display of THE GLOVE, turned inside out so we can have a good look at the congealed yellow stuff.

Nice.

Note to self:

Take care what information thou doth impart to those under seven.

For verily, thou canst not take it back.

Anyway, we are trying to look on the optimistic side. You certainly have to applaud Junior Aust, and her younger sibling, for their impressive curiosity. Even curiosity into slightly gross stuff.

Which explains why I found the cartoon at the top of the post, from the brilliant xkcd.com, so funny when I saw it earlier this evening.

Now, Mrs Dr Aust and I have sworn an oath, in blood and in at least two languages, that the Aust-Sprogs are to be discouraged at all costs from going into any career related to science, or into medicine.

But there is, I fear, the chance that genes, or conditioning, will out.

Time, I guess, will tell.
