Acetylene demonstrations

Another demonstration to show chemical energy. Chemical energy is TRANSFORMED into heat, mechanical, sound, and light energy. Not a single joule of energy is created or destroyed...EVER.

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.

@ksendelw We were not trying to deceive anyone. The lesson was about combustion and chemical energy and not the origin of the carbide. It was a quick mention to 6th graders that have not had chemistry yet. This is meant to get them excited about science.

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

as long as there's teachers like this there's some hope for today's kids... sadly they're few and far between

hm.. pretty keww

i was watching laptop reviews.......how did i find this?

@Nanovirus5995 haha my teacher was kinda like this he set off 2 liter dry ice bombs behind the school

@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.

@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.

@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 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.
