Nope.

when your teacher is trying to teach you how to cast fireball

+3 to Intellect

If anybody’s wondering what’s happening here, this clip made it onto Outrageous Acts of Science, and they explained that this teacher was demonstrating the Leidenfrost effect, which is basically when you place a droplet of a liquid on a surface that’s far hotter than its boiling point. The part of the drop touching the hot surface turns into vapor and forms a cushion that the rest of the drop rests on top of, which causes it to skid across the floor so quickly.

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.

My mama said I can’t be in yo class no more

Hey uh doll hi hello 1. You said talk about donuts in your bio so you’re automatically a fave and 2. You said you were bored and wanted prompts so imagine Tony and Bucky sharing a glazed donut and just being happy! And probably also on a date or maybe on the roof of the tower watching the sun set whilst Bucky toys with the wedding ring he has in his pocket y’know I think that’d be okay? Idk sorry if I’m being annoying

This took approximately 25 years to fill and it probably wasn’t worth the wait lmao I’m sorry ;; but I had a lot of fun writing it.

If there are typos then that’s all completely my fault. I’ve got no beta. All I have is Google Docs and spellcheck.

Maybe it’s a bit of a cliché scene, the both of them lounging around on a couch they dragged out onto the landing pad. But it’s comfortable; there’s no flashing cameras, no invasive questions, and no furtive glances. Just the two of them (and okay, maybe one flashing camera, but that’s just because Tony insists on taking selfies).

“I’m still upset about the Boston creams,” Tony grumbles, a chunk of glazed donut in his hand. He pops the donut into his mouth, sucking off some of the dried glaze that covers his fingers. After swallowing, he adds, “The lack of them, to be more specific.” Although, they did stop by the shop near 6PM, so he supposes he can’t complain too much.

Bucky hands Tony another chunk before polishing off the remainder. “I feel like it’d be harder to share a Boston cream,” Bucky says, actually pondering the logistics of sharing such a donut. He gestures vaguely at Tony’s jeans that probably cost more than what most people make in a week. “Do you want a bunch’a filling all over your pants.”

Seizure First Aid.

Learn it. Share it. Know it. Use it.

100% correct medical information on tumblr for once; also consider calling 911 if you don’t know how often the person has seizures and ESPECIALLY if the seizure has lasted 5 minutes or more (which is why the watch is critical)

I have epilepsy so making sure the word is out on how to help people who do have seizures means a lot to me.
