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.
THIS MADE ME SO HAPPY I DONT EVEN KNOW HOW PLEASE I ADVISE YOU GUYS TO DRAW ALONG WITH BOB ROSS IN MS PAINT IT IS AN EXPERIENCE I AM SO CONFUSED BUT PLEASED FUCKING DO IT
Bob Ross teaches you using layering and color theory, which are principles which work no matter what you paint with. Some materials won’t blend the same as oils obviously, but as Ross himself said, “you can paint with almost anything.”
Paint along with whatever you have, it’s great practice.
Remember in 1993 when Jurassic Park was like…the end all, be all of special effects?
not gonna lie that still looks intimately real
I’m still somewhat convinced that someone sold their soul to create the special effects in Jurassic Park because that shit is over 20 years old and it still really, really holds up, better than the stuff in a lot of current movies, even.
Fucking witchcraft, man.
fucking look at this shit though
Literally see this post flying around with a few different responses added to the bottom each time so I’ll say it for this one myself:
THEY ACTUALLY BUILT A GIANT MASSIVELY DETAILED FUCKING ANIMATRONIC T-REX FOR ALL OF THIS THAT’S WHY THE EFFECTS ARE SO GOOD. CAUSE IT AIN’T CGI. AND IT AIN’T GUY IN A COSTUME. IT’S A BIG FUCKING ROBOT DINOSAUR. AND EVERY PART IS DESIGNED TO MOVE. IT COST LIKE HALF THE BUDGET OF THE FILM.
amazing
And they had the film it in small increments, especially in the outdoor scenes, because the rain fall kept soaking into the ‘skin’ of the rex and would slow down and mess up its movements. So they would stop filming and have a crew out there drying off this massive, fake dinosaur, and then they’d start filming again until it was too wet. Repeat until the end of the scene.
They used animatronics and detailed costumes for most if not all of the dinosaurs in the first movie.
The triceratops for instance, was also animatronic.
One of my favorite anecdotes I’ve read on tumblr is how the t-rex robot from Jurassic park would malfunction while it was drying out. How did it malfunction, you might wonder?
Motherfucker randomly started moving.
So apparently if you were on the jp set you would sometimes hear people screaming bloody murder even though they were all well aware that it was a giant animatronic puppet and wouldn’t actually, you know, eat them.
Did not know this, had to reblog for awesome movie history insights.
So, I knew about the animatronics bit but I did not know the raptors were guys in suits and the malfunctioning t-rex sounds terrifying.
And i just googled malfunctioning t-rexand was not disappointed. Apparently in order to put the skin on over the steel frame a guy had to crawl inside thet-rex while it was turned on and glue the skin down. And if somebody turned the t-rex off or the power went out the guy in the t-rex stood a very real chance of getting mangled and killed by the hydraulics.
So of course, the power goes out.
And this guy is still in there gluing the skin down.
Apparently the way to survive getting sheered to death by huge sheets of metal while you’re inside a giant t-rex robot is to curl into a ball and hope for the best.
And this guy hoped for the best and got it.
Some other people on stage pried open the t-rex jaws and glue guy crawled out of its mouth and was totally okay.
This is getting better and better.
I think they only had like 6 minutes of CGI
I’m just waiting for the T-Rex to come to life and leave its stand.
The thing about this that gets my special effects nerd going is the fact that EVERY single dinosaur was sculpted by artists based on the current existent archeological evidence of the time.
Even better than that, this movie ADVANCED our best understanding of dinosaurs at the time. They were blowing out a budget bigger than anything Hollywood had ever seen, and along with employing almost the last hurrah of incredible physical FX, they had a bank of those newfangled digital SFX computers. Nobody’d ever really created convincing dinosaurs in a movie before. It’d all been stop-motion animation, and even when the models were exquisitely crafted, you could just tell there was something OFF about them. Spielberg wanted THE BEST DINOSAURS EVER, and he figured on using the cutting edge of digital modeling and animation technology to build them for him.
So they got hold of some of the best paleontologists they could find and said, “We want you guys to take this tech that your labs could pretty much never afford and use it to build us the most realistic, accurate dinosaur models the world has ever seen.”
The paleontologists knew an opportunity when it bit them in the ass. They plugged in everything they knew about dinosaurs, all the skeletons and their best guesses about soft tissue and all that. And when they’d created those dinosaur models, they had the computer start moving them as they realistically would with anatomy like that. One guy took a look at those walking t-rexes and velociraptors (really utahraptors, but whatevs, fam), and he said, “Wait a minute, I’ve seen movement like that before.”
He called up film of a chicken walking. Everyone in the room said, “Holy shit.”
Prior to 1989, the idea that birds were descended from dinosaurs existed–we knew about archaeopteryx, we knew there was some minor connection there–but the idea that DINOSAURS LIVE IN THE MODERN WORLD AND THEY ARE CALLED BIRDS was not pre-eminent. Jurassic Park changed our scientific understanding of dinosaurs.
That paleontologists’d be Kevin Padian. Who is awesome.
gwendoline christie utterly epitomises the “get u a girl who can do both” meme. girl can stalk across a scorched battlefield dressed in full armour & covered in men’s bloodAND float down the red carpet in a gorgeous flowy dress and high heels looking like the actual personification of spring and sunshine. warrior harbinger of death and floral goddess. when will ur fav ever. when will anyone get on gwendoline’s level.
#okay now I need the movie #where they’re the four horsepersons of the apocalypse #except they’re all a bit disgruntled with their job assignments #so they decide to throw a spanner in the works #it would be like good omens but with more stabbing
(tags via @madmaudlingoes and may I just say that is an awesome idea? XD)
