School Facts That Flunked the Test of Time

Did you know that some stuff we learned in school isn't exactly on point? Like, remember when they told us you could drink water from a cactus in a survival situation? Turns out, that's more of a Hollywood thing than reality - most cacti have toxic fluids that can make you sick. And what about Pluto being the ninth planet? Nope, it got downgraded to a "dwarf planet" back in 2006. Oh, and don't get me started on how they used to teach that dinosaurs were cold-blooded - turns out, some of them might've been warm-blooded like modern birds! It's wild how science keeps evolving and uncovering new truths.
