I feel like this cat lives in a small cottage in the woods somewhere that you only find when your lost and that when you enter she will tell you some Chilling Tales while you sit by the fire together
The substance the teacher uses in the video is liquid methane. But methane has a really low boiling point. Like, about −160 °C low. So once it touches the comparatively hot floor, the Leidenfrost effect comes into play, and it slides across the floor. The issue is though, methane is colorless, so you can’t normally see it. Thankfully (in this demonstration), methane is also very flammable, so he sets it on fire before dumping it onto the floor so you can see it as it moves.
Definitely a cooler demonstration of the Leidenfrost effect than dropping a little water in a hot pan.
Or hotter, if you like puns.
THANKS FOR EXPLANATION SCIENTIFIC SIDE OF TUMBLR
My mama said I can’t be in yo class no more
how the heck did he get past health and safety to do this
the American public school system has no concept of health or safety
You guys with your earthquakes, tornadoes, and hurricanes are all crazy. As much as I grumble about snow I’ll take the blizzards and occasional flooding of the northeast any day over that chaos.
Look sometimes the sky decides ‘you know what fuck this’ and tries to kill you, and that’s just how it is.
The mystery of the glorious fireball emitted by microwaved grapes (featured in my novel Little Brother) has been resolved, thanks to a paper in the Proceedings of the National Academy of Sciences
in which Trent University researchers Hamza Khattak and Aaron Slepkov
explain how they destroyed a dozen microwaves before figuring out that
the grapes were just the right size and had enough humidity to set up
standing waves that amplify the microwaves – and anything roughly
grape-sized will do the same.
The paper is offline at both PNAS and Sci-Hub, which is weird, but there’s good coverage of it at Ars and Wired.
I call this one “A Burning Passion” because I love puns.
I also love Jane Austen’s books thanks to my wife. I love the aesthetic of the times, the formality and the simplicity of the stakes in the fiction. It’s a happy place for me. Anyhow, if you know someone who likes similar things and fire… spread the word like a cleansing flame.
Today in chemistry we did a lab where we burned different chemical compounds to see what color flame would be produced and my group mixed all of the compounds together, and this was result
Russian soldiers witness the awakening of an elder god.
Why does this stuff always happen in Russia? What are they doing?
Reality decided that’s the only place where it can cut lose, considering they don’t seem to give a fuck about anything.
“According to some of the YouTube comments, the fire was caused by burning zinc, and the screaming came from the underground pipes that had somewhat of a ‘flute’ effect when the air passed through the tubes.“
