I didn't start the thread because I was sleeping. I took a redeye flight back from Seattle Tuesday night/Wednesday morning and needed to go to bed early Wednesday night. I DVRed the episode, since I can do that now.
And in talking about Ms. Byron, can we please remember that this is a public forum and Kari herself is active on the Internet? I doubt she'd pay attention to this forum in particular, but you never know. In any case, she deserves to be spoken of with respect.
Ancient Torpedo: This was a cool one. I wish there were more information about the origins of this torpedo. The background Adam gave was kind of vague, and it seemed as if the information came mostly from modern sources.
I loved the water-pressure rig Jamie came up with to bend the steel into the desired shape. That's just brilliant. Water is powerful stuff.
I think they were too quick to go for modern rockets over black powder. Their problem throughout was that the rockets were just too powerful. I have to question whether the rockets they were using really were "equivalent" to black powder in the ways that mattered. At least I would've liked to see some small-scale tests comparing the different technologies. (I haven't checked out the aftershow or deleted scenes yet.)
It was wild watching the torpedoes fly around the way they did, though. And it was a good point that accuracy wasn't as important in a real battle situation where there were multiple ships to shoot at, and probably multiple torpedoes to fire off.
Wine bottles: I agree that they sometimes define the myths too strictly. The important part of the myth is that the popping corks did sound like machine-gun fire and the corks flew a fair distance. At least they should've said that most of the myth was confirmed even if one component was busted. Or they should've called the whole thing plausible. Who knows? Maybe the truck was on a slope and some of the corks rolled downhill after landing, thus ending up over 100 feet away.
Otherwise, the whole thing's pretty straightforward. Heating a pressurized vessel = kaboom. And it's no surprise that it'd be quiet at first and then make a lot of pops in quick succession. Popcorn behaves the same way, and pretty much the same operating principle applies -- heat expanding gases in a group of near-identical pressurized chambers until a rupture point is reached.
