343,000 FPS Phantom camera rolls as Pyrex cookware shatters from thermal shock

  1. We’ve seen The Slow Mo Guys pop bubbles at 2,500 frames per second and record a DSLR camera’s shutter activate at 10,000 FPS but for their latest video, the duo brought out the big guns. I’m of course talking about the Phantom v2511, an insane high-speed camera that can record in excess of 343,000 frames per second.

    In this video, the guys tinker with thermal shock using some Pyrex measuring cups. Apparently if you drop cold water (or as you’ll see, nothing more than air) into a very hot Pyrex measuring cup, it’ll shatter violently. Lucky for us, The Slow Mo Guys were able to capture it in glorious… well, slow motion.

    As the frame rates climb, resolution unfortunately drops but you can still see clearly what’s happening at 343,915 FPS.

    Fun fact: a 5.1-second recording at that insane frame rate generated 19.5 hours of footage.

    This only works because Pyrex isn't "Pyrex" anymore.

    For 90 years, Pyrex was borosilicate glass, which could withstand extreme temperature changes. Corning sold the name, and since 1998 Pyrex sold in the US is plain old glass.

    Seems like plain old glass indeed. The pyrex glass I knew was hard to break at high temperatures

    It is indeed plain old glass. Well, soda-lime-silica glass, which is the most common form of glass. The guys touch on it at 0:28 in the video.

    So what you're saying is, I should probably keep the old Pyrex I have in the house... Got it.
