As of two weeks ago, we've officially had two episodes dealing with shipwrecks. EP016 / "Pokemon Shipwreck" (Original US air date: 29 September 1998) A cruise liner known as the St. Anne has gone under. It's resting upside-down on its smoke stacks, which in turn are resting on a piece of rock that's jutting out from a crevice. In the episode, passengers who have survived the sinking are still alive underneath, as air pockets exist in what were the ship's lower levels. 1. An early "gag" sequence has it that any undue shift in the weight of the people or animals on board will cause the ship to tilt; it's explained as being a result of how heavy everyone and everything is. But how much weight would be necessary to cause such a situation? (In the episode, the situation is resolved by having everyone recall all but the most essential mon back to their pokeballs, which converts them to weightless energy in storage; not even long-time fans of the franchise can explain how this works, so we'll just go with it.)2. The escape plan calls for them to get to the bottom level of the ship and cut a hole in the hull. Once the water comes through, they'll escape by hanging on to water-type mon (who can presumably swim their way to the surface). A. How much heat would be necessary to cut one's way through the hull of an average cruise liner? B. No water is shown pushing through the cuts; a flow only happens when the hull is completely cut through. How realistic is this? C. Would it have made a difference where they cut the hull? They're shown having to traverse several levels to make it to the bottom. *all answers based on my own experience 1: it depends on the balance of the vessel, but it is theoretically possible to have it balanced such that a very small weight will cause it to become unstable. 2A: welding torch level heat 2B: plausible - the air is compressed to the same pressure as the water, so a small cut will have minimal leakage. 2C: it would make a difference in the thickness of the hull, but I don't know where the best place to cut would be. On the topic of cutting metal underwater, how do they do that? This is me trying to understand it than critique the show. You can't use a regular oxy-acetylene cutting torch because the water on the other side would act like a massive heat sink and prevent any melting thru. Underwater welding has to use electric currents. Even that is pretty specialized equipment that most likely wouldn't be carried by a civilian passenger ship.

I am reminded of a science experiment we did when I was a kid. You took a paper cut full of water and placed it in the center of a hot camp fire. It took over 2 hours for the cup to burn up because it had to boil off the water inside it. I imagine trying to use a cutting torch the hull of a submerged ship would be similar. You can heat all you want from the inside, but the water outside would prevent any complete melting of the metal.

well, at this point, I think we've answered the question quite satisfactorily.

AG 082 / "A Shroomish Skirmish"Original US air date: June 11th, 2005Four individuals are being chased by wild animals - *Male, approximately 18 years old *Female, officially stated to be 17 *Male, approximately 15 years old *Male, officially stated to be 10 The four blunder off of a cliff, but are saved when one of the four deploys one of his monsters. The monster hits the ground before they do, and immediately creates a whirlwind that breaks their fall. The height of the cliff isn't even hinted at, and so there would be some give-and-take as to whether or not there would have been time to deploy the monster. The person is also shown throwing it at the ground, possibly justifying how it reached bottom first. But that still leaves the issue of whether or not a whirlwind of any form could cushion a person's impact with the ground. Same concept, different episode - SM014 / "Getting To Know You"Original US air date: 17 June 2017This time, a 10-year-old girl and a fox critter the size of a large house cat go off the side of a two-story building. A vertical gust of wind breaks their fall.

Ever hear of indoor skydiving simulators? There is one quite close to me that uses a vertical wind tunnel that is strong enough to push grown adults into the air. mk.xscape.co.uk/attractions/iflyIn theory a strong enough wind at just the right time could slow a child fall from a building, and cat sized critters could probably survive on their own.

Pokemon Sun & Moon episode #16 (unaired in US as of this posting) bulbapedia.bulbagarden.net/wiki/SM016It's been established that seal critter Popplio is able to generate large bubbles, presumably of water. They're so large, and so stable, that it can actually slip inside. It's trainer is hoping that one day the bubbles will be big enough for humans to ride inside (so as to make underwater adventuring more plausible), but for now it's just other critters. A series of blunders leads to Popplio and Rowlett, an owl critter, being trapped inside of a bubble and blown halfway across the island. When the bubble finally pops, Rowlett desperately tries to keep the pair airborne, but they crash-land into a parabolic array being set up by the bad guys and inadvertently make off with a critical component in their efforts to escape. 1. The part they make off with is a metal loop of some kind, just large enough to get caught around Rowlett's wings. What sort of part could that be? edit - The part's in the blue-haired guy's right hand. 2. What kind of bubble would we be talking about to even begin to behave like what we see in the episode? 3. Owl trying to carry a seal cub. How much failure are we talking here?

it could be an element of the antenna, or a waveguide, either of which would affect the function of the array. as for the others, magical creatures doing magical things.

Carry a seal pup? I doubt it for example at birth a Harp Seal is around 3ft long and weighs about 25lbs, even the largest Eagle Owls can only carry prey a few pounds at most.
But as LTW say, magical creatures so not really testable.

What type of owl?... ??... As MrF above says, at birth, seal cubs are heavy, above the carrying weight of any Owl I know of. 25lbs is about the maximum weight a Human can carry for any distance, above picking a sack of say Spuds up and throwing it on a truck. In fact, thats about a good analogy to imagine, a standard [retail] sack of spuds used to be about 25 lbs more or less?.. Heavier sacks for wholesale are/were available. Can you see ANY bird of prey carrying that weight for any distance?.. I suggest maybe even a bit much for the Bald eagle or Golden eagle, "over any distance at all". Yes birds of prey will tackle say newborn sheeps, or even seal pups, and still-born ones are common prey to any raptor, but mostly they will take chunks of that away, not the whole carcase.

Eagle Owls are a match for any Bald eagle or Golden a Eagle in carrying capacity,,the most they can lift is about 3-4lbs as well.
As you say they could kill one or scavenge a dead pup and eat chunks of flesh.

Sun & Moon episode #18not yet aired in US bulbapedia.bulbagarden.net/wiki/SM018Mallow and her older brother are heirs to the family restaurant. At some point before the start of the series, her brother began traveling around in order to collect new recipes, at which point he would send the more promising ones back home for testing. It's in this capacity that he found a recipe for a nearly-forgotten stew that was once a popular seasonal meal. Thing is, the reason why it was seasonal is because a key ingredient used for flavoring - a type of nectar - is scarce outside of a particular season. To compensate, Mallow has franchise mascot Pikachu fire off what is essentially a lightning bolt into the pot of stew she's making in the hopes that the electrical discharge will provide a unique enough flavor to be a substitute. However, this inadvertently electrifies it. The bowls and spoons she serves it in are wooden, meaning that nobody knows it's electrified until they go to eat it, at which point they get a bit of a jolt. Cue Mallow getting a lecture by both one of her classmates *and* her dad, who comps everyone a proper pot of stew. 1. Can introducing direct electricity into a stew change the flavoring above and beyond an additional level of cooking? You can in fact cook meat with electricity (a simple enough experiment involves cooking a hot dog), but this is premised on the flavor being changed in a noticeable fashion. 2. Is it possible for something that is cooked with electricity to remain electrified?
