I'm fairly famous here, I basically scavenged an abandoned laboratory complex with /sci/'s help, several months back. It was quite a drama, and you evidently have no right to call me a newfag if you don't know who I am.

>>1670941

I recall it wasn't, might be mistaken I suppose, it's not something I've checked recently I must confess. I don't have a decent magnet to test it with, the fridge door didn't seem to affect it though.

>>1670954

That's ferrofluid...?

>>1670894

If I don't mention it, someone always asks within a few posts.

Not sure what you're trying to achieve tbh. Also mercury isn't magnetic.

Greetings /sci/

I've been given a small pot containing about 2ml of mercury. I'd like to keep it in a sealed vessel for curiosity's sake, but it's picked up a bit of dust it seems, and has bits floating on the surface.

I gather that one can clean it via distillation, but I'd rather not vaporise it as I lack a fume cupboard. I do however have all manner of lab glassware available.

Filtering springs to mind, but I'd think it too dense to go through the paper; while I do have coffee filters available, I'd rather not waste time and mercury trying it if it's likely to fail, especially as I'd be contaminating various things in the process.

Also, how can one safely clean anything that's been used to contain mercury? It seems to like to stick to the sides of glass vessels in tiny droplets, and I know that washing it down the drain is a very bad idea.

(And to save the inevitable question, yes I am 'the' Hornet)

Very good guess, it's Methylated spirits, slightly impure so the flame is blue/yellow by default; I added enough boric acid to make it slightly green rather than full-on emerald, and the result is usually a three-colour flame when rolling on one's palm.

The difference being that only I'd know how to light the thermite, and until I do it's completely safe. With acid I'd have to constantly keep an eye on it. I'm doing non-newtonin fluid with cornflour, but I think the host'd value his speakers. Might be able to with clingfilm maybe... nifty idea, cheers.

Thank you kind sir, I have a few solvents at my disposal, hopefully at least one will be of use.

>>1660237
Certainly sir - http://www.youtube.com/watch?v=Rc0KW7kXBDo

I have a gas lighter, which would be better than deodorant, as I could release pure butane and light at will. Only problem is I lack either a leather glove, or calcium powder. Interesting though, I'll file it for future reference.

I'm aware of that first one, I mentioned it earlier in the thread as something I couldn't do due to safety concerns (you don't take conc H2SO4 to a party with drunken people around).

I'd not heard of the other though, will do a bit of research, cheers. :)

bump in hope of an answer

Bump.

Not all sociopaths are deranged killers, I should point out - they just lack emotional connection. Sure there'd be a lot of Dexters out there, but I'd probably prefer that to a herd of people who can't think.

Anyway, could we go back to the topic at hand, if anyone has any further ideas for chemistry-related entertainment?

>>1659771

Do people like you actually stop for a minute and think that people do actually try these things? Or is that the point, you want some random person to gas themselves for the sheer heck of it? :\

Bumping. Pic related, it's one of my portable fireballs.

>>1659725
A bit too evil, and not quite the definition of 'trick' I was after. Cheers though. :)

Sounds like a variation of the screaming jellybaby? In which case I'd need to obtain perchlorate or similar first.

>>1659625

Batteries do seem the way forwards, although I recall them getting worryingly hot when used that way.

Lycopodium gives me an idea though, small amounts of non-dairy creamer could be blown through a flame, for the same effect.

Elephant toothpaste sounds a good one, but not sure peroxide is something I'd want to have/use at the party. I had to rule out the sulphuric acid/sugar carbon snake for the same reason. Cheers for the ideas. :)

(For anyone wondering, I am 'the' Hornet... I'm using the same tripcode, but the hash seems to have changed from the old !!Ycp for some reason.)

Well, I suppose I could do the thermite indoors, that'd certainly work. :)

I'm off to a fancy dress party next week, and have decided to go as a 'mad scientist'; lab coat, goggles, mad hair, ash on face, exotic glassware with glowing liquid inside (no shortage of glassware here, and a few glowsticks can donate their contents), etc. Should be a good shindig, especially as a fair few of the guests know of my past exploits.

Hence, I'm looking for more ideas for tabletop chemistry party tricks I'd be able to perform. Pic related, it's sodium acetate crystallising, one of my first ideas. Quite safe and fairly interesting. Another idea is my patent hand-held fireballs, which is still a work in progress, but at the moment I have the blue/green/yellow one finished. When I'm done with them I'll post creation instructions on /sci/ and elsewhere.

Another idea is bubbling hydrogen gas through soapy water, to give a rising column of flammable bubbles. Not quite sure how best to make the hydrogen bubbles in situ though, aluminium + sodium hydroxide probably isn't too safe to use at a party.

The host has agreed to lose part of his lawn to thermite, so that's on the cards for the evening... any other ideas? The classic 'screaming jelly baby' is also a possibility if I can get my hands on some potassium permanganate/perchlorate in time.

Also, she doesn't impart motion via contacting the coin, she manipulates magnetic fields to progressively tug the coin faster & faster. It's more like a midair railgun than a conventional firearm.

Different mass? Same reason a human doesn't shoot backwards at the same speed as a rifle round while shooting a gun. Also Biribiri ftw.

I'm not a graduate, so can't comment, but you wisely deployed a Nagato; helpful bump.

Speaking of burette failures, how can one un-stick stopcocks? I have about a dozen bits of glassware with sealed stopcocks, including a couple of burettes ... I'd not be happy trying to simply force them.

Apparently so. I'd expect some could even last longer, if the plants were small enough to fit a quantity in there, and reproduced without insect intervention (eg mosses use spores). Bonsai need constant care to keep them trimmed to size, you could have an open terrarium with them yes, but not a sealed one.
