Yayy, Kari's back! And without ceremony -- no acknowledgment of her return, no farewell to Jessi. That part's disappointing, though I'm just glad she's back. And yes, motherhood agrees with her aesthetically, to put it tactfully.
"Dive to Survive": What movie or movies did this myth come from? I guess it's pretty common, and I'm sure I've seen it here and there, but often they cite a specific film even if they don't manage to license the actual footage.
I'm not surprised that the water surface proved effective at blocking the shock wave. After all, a shock wave is basically a really powerful sound wave, and we know that sound has trouble penetrating the boundary between air and water.
And once again, we see that the more powerful an explosion is, the less visually spectacular and fireball-y it is. Something I doubt Hollywood is ever going to acknowledge.
Phone-book bulletproofing: Again, I'm surprised that they didn't specify what show this myth came from. They said it was from a TV spy show, but didn't give any specifics about which one. I'm wondering what it could be.
I don't get why they called the myth busted when it was actually confirmed for handguns. I guess they were defining the myth as that a single layer of phone books could make the door completely bulletproof, but that's a little too absolutist. That's one reason I'd like to know the source of this myth -- in the spy show, what kind of guns were used?
Interesting discovery, that it matters whether you put the phone books in front of the glass or behind it. Nice little physics tidbit there. The soft stuff in front doesn't matter much, since the bullet doesn't really lose energy until it hits the rigid glass.
I liked it how Kari's hypothetical situation was basically the plot of the fourth act of every single episode of The A-Team. I'm surprised they didn't do this one on that show.
