Video: Drop a lit match in water, and it will immediately be extinguished. But model rocket engines, made mostly of potassium nitrate, sulphur and charcoal, will burn all the way through even when completely submerged. As this high-speed footage reveals, to test a rocket engine's apathy to H2O, you'll want to find something stronger than a glass fish tank for your experiment.

Video: To the naked eye, someone slicing through steel using a high-temperature plasma torch just looks like a massive shower of sparks. But through the lens of a high-speed camera filming at 480 frames per second, the steel looks about as strong as melting butter as the torch easily slices through it.
Video: Despite only giving you about a second of excitement at launch, model rockets are still a fun way for us (non-billionaires) to live out our dreams of space travel. But have you ever wondered what's happening inside a model rocket engine while you're standing a safe distance away from ignition?
Video: The folks at YouTube's Warped Perception channel promise that this video simply shows a mouse trap slicing through a plain old hot dog. But when filmed at a mind-boggling 147,000 frames per second, it's hard not to imagine the same thing happening to a finger accidentally getting caught in there -- or something, uh, a little more genitally inclined.
