This is a flame rainbow, the ROYGBIV of fire created by adding methanol to different ionic salts (listed in the screenshot above in their respective tint), which result in the various flame colors. That’s cool. I was sort of hoping for one flame with all the different colors layered like

Ever wonder what it looked like inside a spinning CT scanner? Well wonder no more my curious friend (are you a cat?), because this is a video of exactly that. I always assumed it was just two wizards making a donut shape and pointing their wands at the patient, but

Both the top and bottom half of the image have the same number of dots, but the ones on top appear to disappear unless you’re looking at them. This is an example of a Hermann grid illusion, an optical illusion first documented by Ludimar Hermann in 1870. According to SharpBrains,

Seen here looking like the radioactive waste produced by my roommate, this is a short video utilizing a green laser to visualize the atomized plume caused by a toilet being flushed. I don’t want that sparkle bomb touching my butt! So, what’s the lesson here — stand up and close

Because important scientific experiments take many different forms, this is a video of Youtuber HaerteRest packing a toilet bowl (and every other hole he could find) full with over 1,000 sparklers, then taking the toilet to the great outdoors to see what will happen when they’re all lit. SPOILER: it

Using a “hard to acquire” laser diode (I suspect the black market was heavily involved), Youtuber styropyro went and built what is allegedly the world’s brightest laser pointer. Based on that photo alone, I’m apt to believe him. The green laser is so bright “you need welder’s goggles to be

Because some people have all the fun, this is a video of Youtuber The Backyard Scientist destroying things with a 400MPH rocket powered slicing warhead he constructed from six kitchen knives. Is this actually science? Yes, and the best kind: the DANGEROUS kind. *twirling tips of evil villain mustache* Yessss,

A recent study conducted by researchers at the University of Sydney has found that octopuses will intentionally throw shells and other seafloor debris at one another, with about 66% of the throwing activity performed by females, and often aimed at males who are harassing them. “Piss off times eight, loser!”
