Surface Tension, Cat Spit, & Friends
Here’s a story. It’s apropos of nothing, but I’ve been too busy to write enough here, so I thought this would make people smile.
I could go on and on about how it’s a story of Social Networking, and how sometimes the world is a better place because we’re closer, or at least more able to contact people for random bits of meaningless and make friends.
It could be a story about how we’re not so distant, or maybe how we’re differently distant.
But it’s not, because then I’d feel the need to actually do a bit of research to support my theory, and post it on mettadore.com, which I know plenty of people are sick of. So, rather than anything meaningful, it’s merely an amusing anecdote.
I was at work, drinking maté, typing away, la la la, work work work, data data data, la la l–
AHH!
I spilled maté on my mac!
Well, the story’s a happy one, because, as you can see from the image of my tweet, physics saved me. That’s not always the case. At certain times, physics is a right bastard, particularly when I’m on my skateboard, or ice skates, or standing on my roof trying one more time to get my Superman Underroos to do their damn job!
Anyway, physics is sometimes a bastard, but this time it was cool.
So today, I got an email message from someone that made me chuckle:
Hi John-
Google led me to your tweet from 1/28: “The surface tension of water is strong enough that water won’t flow into certain sized holes… like those of a MacBook Pro’s speaker.”
I just spilled a (small) bit of iced coffee onto my 15″ 2008 MBP left speaker grill, so the topic is near to me… The coffee seemed to just sit on the grill for the couple of seconds it took me to wipe it off. My empirical evidence supports you theory.

First, I looked on the web for teardown photos to see where the microphone was. No luck. Since I’m wondering if I might have any trouble, I was wondering if you had any more background for your MBP speaker/surface tension info.
Thanks!
I thought it was pretty funny that someone would actually look up “surface tension” or something like that- what a total geek. What was funnier was that I actually looked it up, and started to do a calculation the day it happened, just to see. Now “that’s” a total geek!
Anyway, I sent a message back, mostly to be funny, because I always feel both funnier and more helpful when I connect to someone through social networking.
Hi! Wow, pretty funny connection. Social Networking FTW!
So, no, nothing. No problems and no later developments. I did calculations of surface tension in grad school and the size of those holes are, in fact, too small. However, I will give the caveat that certain things increase or decrease the surface tension of water. “Uh oh? Where’s he going with this?” You ask.
For instance, cat spit. I have some knowledge of cat spit, and it decreases water’s surface tension. Don’t ask me how I know this, it’s an embarrassing situation that I’m still in counseling for. Suffice it to say that if you have a cat, you may want to be careful letting him drink beverages around your laptop (The whole “lack of a thumb” thing is hard for them, but I’ve learned that now, and we’re moving on)
Anyway, I’m not sure where coffee is on this. Whether it increases or decreases it. However, even if it decreased it, it would have to be an insane amount to get into that grill. My suspicion is that the Apple engineers are somewhat sloppy drinkers, and have thought about everything– based on they’re own klutsy habits!
I think your safe. Yay Mac!
Hope everything else is equally peachy.

The whole exchange got me thinking about my New Year’s Resolution for 2009, which I’ve re-resolved for 2010. That was “to be more Irish.” It’s a tough goal. Being Irish is nothing to sniff at. It’s no easy feat, but I’m convinced I can do it if I work hard enough. This exchange bodes well, because the Irish have a saying that a stranger is just a friend you haven’t met yet.
This person shot me an email out of the blue, and email to a stranger, and email to a friend she hasn’t met yet. That’s the cool thing about social networking. We’re all friends.
Yay for Social Networking! (and yay for the Irish, too!)
