Calcium carbide is not a mined rock, it is produced in blast furnaces from Coke (C) and Lime (CaO). Coke is made by pyrolysing coal, and lime is made from limestone also in furnances. A fun teacher, but not a great one, got to get the details right. Teaching by making up the details on the spot isn't so good for the kids that are smart. "Carbide" was so fun growing up.
What a Fantastic teacher! Hands on, nitty gritty, outside, in the sun, exciting and informative! That's how science should be taught not with health and safety up the ass, inside a class, behind hundreds of screens of plastic, watching a gummy bear melt ¬_¬ I Love this video :D
@Nanovirus5995 Science can be fun and exciting when you're in university, but I'd rather not watch somebody's skin bubble from a spilled material during a rather "nitty gritty" experiment ever again. Children have potential but they make stupid mistakes. There are so many reasons why they get health and safety "up the ass", any science-minded individual would recognize that.
@MegaBoners I do agree that it is there to keep individuals from getting injured however most of it is common sense. It's somewhat humourus to me when I used to read bottles and it said "Suphuric Acid, DO NOT DRINK". It's a bit obvious not to but anything to keep people safe I guess is for the greater good.
@Nanovirus5995 Those labels would seem like they're really obvious, but you would be so surprised how stupid some people can be. I knew a guy who in grade 10 science (which at this point he should have developed some sort of brain) ate a piece of litmus paper just to see what would happen. Not the most dangerous thing, but also not the most intelligent. Same guy also tried to light his fart on fire and tried so hard he shit his pants in class.
@xfubar He sounds like a clever man /: ) It's just a bit disappointing really to hear that I'm part of the same race of creature that end up doing these sorts of things for social respect or status.
Yeah... pray you don't have any static discharge... My buddy blew himself through his garage door. Yeah. He was fubar for quite some time after that little trick.
@welderboy14 so at lunch time you get the rocks out and mix water and fill up balloons with acetylene that's crazy. but all bullshit aside why cant a teacher teach some kids some cool stuff that many dont know.
@cbr900rr919 allright good to know i wam talking to a City Slicker....Acetylene is used along with Oxygen to Cut Steel...Acetylene Comes in pressurized cylinders Google Oxy/Acetylene Cutting.
@karazze0285 Actually, if you watch the news, you'll clearly see that it's the republicans who have a problem with science. Now get a life you commie. :p

instead of blowing into it, why not just use an oxy-acetylene torch? than you can adjust your mix for perfection...

Thats awesome! We used Calcium in Mr. Fisher's room for an experiment where we put acid on it.
