So, apparently, some people think the snow that fell on Atlanta wasn't actually snow, but some kind of synthetic material dumped on the town by the government in order to cause chaos. The proof: The Atlanta snow won't melt and it turns black when you hold a lighter to it.
Except, that, well, the same stuff will happen to snow when you hold a lighter to it anywhere. In this video, Phil Plait demonstrates the effect in Colorado and explains what's actually going on. The key is that the snow really is melting, you just can't see it. Snow absorbs liquid. Plait has a really good analogy here with snowcones. You pour the syrup on, and the shaved ice absorbs it. Same thing with the snow that's turning to water in the heated snowball. Up to a certain point, the rest of the snow will absorb that water. Heat the ball long enough, though, and you will, eventually, get a puddle. The conspiracy videos just stop well short of that point.
And the burn marks? That's just soot from imperfectly burned butane from the flame itself.
To demonstrate the Magnus effect, YouTuber PeterSripol grabbed a couple of KFC buckets and tricked out an RC plane. The resulting trial and error is mostly the latter.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Fetal lambs survived for weeks in an experimental artificial womb, and scientists hope that the breakthrough could lead to new treatments for premature babies and perhaps the dreamed-of machine utopia where humans are kept mindlessly writhing in translucent plastic sheaths filled with psuedoamniotic liquid. Physicians at the Children’s Hospital of Philadelphia placed fetal lambs into […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
