Magnesium...

[Qonfused]

We did a lab in Chem today, one part involving torching a very small piece of magnesium. And by small, I mean, like, 1 micrometer thick and 1 cm long. Well, let's just say I was blind for 3 seconds. And then I thought to myself: "Now imagine that times 5000 and you have a flashbang grenade."

Heh, really cool stuff.

 

[Lawls]

Old as chemistry.

 

[Da-Muffin-Man]

Well....ive known that for a loooong time now, but when i first saw it i thought it was pretty damn cool too. By the way, there is no way you went "blind" for 3 seconds, it isnt that bright.....

P.S. you can buy magnesium along with all other kinds of other chemicals/stuff that has cool effects while burning. www.unitednuclear.com

 

[Jimmeh]

Pffft, I saw that in a Science class when I was like eleven.

It was pretty cool though.

 

[Ennui]

lol we did that in chem as well

 

[Ren.182]

Lol, i remember when my science teacher (the silly woman) She got a big piece of potassium and threw it in a big glass container full of water. The glass container shattered of course and the classroom was soaked

Was awesome

 

[Shippi]

Yay, us too. Was fun

 

[kirovman]

I remember when we combined two cores of plutonium together above critical mass...

Bad day out, I tell thee.

Last time we did that my friend stole some magnesium and put it in his pocket. Then he forgot, and washed his trousers.

Hmm, have you not seen the potassium/sodium and water experiment?

I put caesium under my foreskin once, needless to say I had the last laugh.

That's seriously tiny. :|

Surprised it blinded you for 3 seconds with that amount.

 

[Qonfused]

Well, lemme clarify: I wasn't blind, blind like "Omfg, I'm blind!" but I couldn't see straight.

OMG RETINA BURN!!!!111111

Have a biscuit, takes the pain away.

Thanks.

Scariest thing I ever did in chemistry at school was make dinitrotoluene, if we didn't keep it cool enough, it would make trinitrotoluene. Oh my golly gosh. And it was the first time we used concentrated acids, my friend spilt some on the tiles and it started eating them :O

At university, we were doing a simple how boiling point changes with temperature. We had to use liquid nitrogen for something, and there was potential for it to cool the air and make liquid oxygen, which likes to explode Although it would take absolutely ages and ages, THE DANGER WAS STILL THERE!!!!

Chemistry rocked me like a hurricane. Making shit explode and stuff. Freakin' ace.

Ethanol is where the fun's to be had. You dribble that crap onto the back of a classmate and set it on fire. They're clueless for about five seconds and then they do this spastic little dance trying to put it out before taking their coat off and stamping on it.

Haha yeah, then you douse someone's family and pets in petrol, light them on fire and see the expression on their face when they come home.

Dude that's like F*CKING EXTREME!!!!!11!!!
The only "chemistry" I ever got to do like that involved a lighter and a can of axe. :naughty:

 

[jabberwock95]

Coolest thing we did was the thermite reaction. :E

We were all peering into a bucket full of sand and thermite out in the playground, we looked round and saw the teacher 20 feet back wearing goggles.

We stepped the hell back, I can tell you.

Dude that's like F*RST YEAR CHEMISTRY for you

Thank **** I've got no more chemistry labs, they were shit. The biology labs we have are awesome, they even have people to clean up after you!

 

[bvasgm]

I was sick the day my Chem teacher made stuff explode...

 

[Tr0n]

I never took chem class.

A friend once poured a whole bottle of parafin over a workbench and set it alight. The flames easily reached the ceiling Was so funny to just see this kid fly backwards as the huge fireball went flying up into the air. Sadly it went out quickly due to quick thinking of the kid. Damn, i wanted to have that day off too because of a fire

 

[Hectic Glenn]

Heated magnesium then placed in a gas cylinder of pure oxygen is really great, you'll need tinted goggles though. Its basically the stuff in flares and fireworks, so bright wow. The alkaline metal reactions are great, caesium in a bucket of water lol, sadly theres only like a tiny amount of francium on this planet. Back to my polyamides, aldehydes and addition polymerisation

? for my bin

I remember going to a few chemistry demonstrations in university. Prof took a small plastic water bottle and filled it with liquid nitrogen I believe. Then he put a very large, very heavy plastic garbage bin covering the bottle while it sat on the floor with the top on to seal it. After waiting a couple of minutes the pressure built up from the liquid turning to gas caused a massive explosion which sent the giant plastic garbage can flying literally 40-50 feet in the air and caused a massive dent in the ceiling of the huge lecture hall the demonstration was being done in. Shards of plastic from the water bottle flew everywhere.

Coolest demonstration ever that I have seen for chemistry.

Words I don't know.

I made hydrogen with something else in a science class. It was kinda cool when I set it on fire.

Lithium is very interesting too. Our sci class tested a whole variety of different elements in water. Explosive fun!

Very small ammounts though and hence they skitted around the surface of the water on fire.
