The video mixes a couple of real biology facts with laundry advice and a human-taste claim that are unsupported or overstated.
Claim-by-claim breakdown
Misleading (88% confidence): Coca-Cola can be used to remove blood stains if hydrogen peroxide is unavailable. Authoritative stain-removal guides recommend cold water first, then detergent or 3% hydrogen peroxide for blood; they do not recommend Coca-Cola as a blood-stain treatment.
Accurate (97% confidence): Pigs do not sweat. Extension and veterinary sources state that pigs cannot sweat or lack functional sweat glands.
Unsupported (78% confidence): Human meat tastes like pork. The claim appears in anecdotal reporting on cannibalism, but there is no strong scientific basis establishing a universal human-meat flavor as pork-like.
Accurate (92% confidence): Some turtles can take in oxygen through the cloaca during winter brumation. Science sources describe cloacal respiration in some turtles during winter brumation, while noting it is not universal and is more accurately diffusion of oxygen through the cloaca than normal breathing.
False (86% confidence): If a human body temperature drops below 25°C, the person remains conscious for only 20 to 30 seconds. Guidelines describe 25°C as profound hypothermia with major CNS depression, and severe hypothermia can cause unconsciousness, but no reliable source supports the specific 20–30 second claim.
