Thanks, everyone. I will either show him this thread, or tell him what the links are.
Ashtar, it’s not really that bad! Certainly not a snotlike texture. Then again, you might not like it.
lel, visual representations might help, since he’s sort of a free-lance graphic artist. You should see the artwork on his band’s website.
ResIpsaLoquitor, you know I like you and all, but honestly… no amount of ducking and running is going to save you from my wrath when it comes!
I mean, really… “What’s tapioca?” Sheesh… I can understand that friend of mine asking, but you? No doubt you’ve been exposed to tapioca pudding at some point in your life (hey, I’m having some right now), so this question is no doubt designed to dissipate my good mood of the moment. If that’s your objective, you have now achieved it. 
Just kidding, of course… I’m not even a wee bit fashed by that comment. (for the non-Scottish: I’m not mad at all) Definitely in a good mood, of course.
Opal, no need to be queasy at all. The stuff’s not that bad… in fact, I know a few non-Chinese that love it. (my brother’s friend Rob comes to mind, in fact)
auRa, it’s not really ammonium chloride, is it? Maybe I’ll ask my sister’s friend Kate to explain mammi and slamiakki to me. (she’s Finnish, though not born in Finland)
Tansu, that looks like a very helpful site and explanation. Thank you.
I don’t know if he is Google-impaired, but I won’t ask. (or at least, not like that: “Hey dude, are you Google-impaired or what?”)
TLD, I’m not sure that it’s all that easy to explain. It’s an Asian drink, made of tea and pearls mainly. I’d search out a link for you, but the search engine seems to be crawling again, Just look for the words “bubble tea” and “Flamsterette_X” under MPSIMS. I’m glad that they at least have it in Australia; if they didn’t, I’d be sort of poleaxed. 
Larry, “Sweat Bubble”? Ick. The mind does amazing things when you try to read things, that’s for sure. They’ve recently changed the lids to a sealed-on cover with funky drawings on it. You have to stick the straw in this cover just the right way, or the bubble tea will splort all over… not good. The straws, however, are the same. They have to be just bigger than the bubbles, right? (then again, you can also order coconut jelly instead of pearls)
Jumvo pea-shooters? The last time I went for bubble tea (about two weeks ago), some of my friends practiced shooting the leftover bubbles out of the straw onto the ground. Quite amusing. 
Haven’t had sweetened green tea flavor myself, but some of the other flavors aren’t too bad. However, if you go to the Dragon Ball Tea House on King Edward and Cambie (I think), do not try the fresh taro. My sister had it once, and didn’t like it. I tried some, and didn’t particularly like it, either. Strawberry isn’t that bad, though.
