Hurricane Windows: As a Midwesterner, I learned this myth as something you should do in the event of a tornado rather than a hurricane, and I was taught that it was not so much about wind per se as about equalizing the interior and exterior pressure, so that when the outside pressure underwent a massive decrease, the inside pressure would be able to escape rather than bursting the house or something. I think I eventually learned that was a myth too.
That Medusa gizmo is rather striking. I didn't know such a thing existed. I guess there are wind tunnels that can produce more powerful winds, but this one's outdoors and portable.
Frozen Head: I called it -- they used pig heads. Fortunately, though, they left it to the end and didn't show it too graphically.
Though I found the use of real human skulls in the ballistics-gel heads almost as creepy. I mean, those used to be parts of people. Smashing them like that seems disrespectful.
The silicone head mold was interesting, though it was rough on poor Kari. I'm a bit surprised she went through with it. I mean, what if her water had broken while she had this thing covering her head and couldn't talk and could barely breathe?
And didn't they already make a mold of her head a season or two ago? I think it was in the episode of bull myths? Maybe the mold didn't survive?
I'm not surprised at the results. Five seconds was way too short, and even with the full freeze, it's not like the body turns completely to ice the way it's depicted in fiction; the connective tissues are still there. And of course the bones are too.
Frozen Tree: Oh, I should've known the Build Team would find an excuse to use explosives after all. At least it was a small explosion, and the tree held up to it surprisingly well.
The whole thing seems like kind of a cheat, though; I mean, if they had an arborist right there on hand, then they must've talked to her beforehand and should've already known that pine trees are adapted to freeze without serious damage. And I'm surprised that, given that fact, they didn't repeat the experiment with a tree from more tropical climes, something that isn't evolved to be freeze-proof.
So pretty much a clean sweep this week -- every myth was busted.
