I believe that the ''gold'' in drinks is real gold, but just tiny bits of gold leaf so it's worth practically nothing. You could put it in drinks to
sell, but just to people who you don't like...

So, we have just opened two methyl-mercaptan cylinder. It was precooled with an ice-salt bath and we've just simply got of it's head (on the third
pics).
You could not imagine what odor it had... On room temperature the 225g of MeSH is a bit more than 100liters of gas.
DO NOT TRY THIS AT HOME

Very nice. The bottle seems old and rusty though. Good that you used it before it leaked

Wow! Looks just like water
What could you possibly need liquid MeSH for? Must have smelled like a mega asparagus fart, fire department getting called, etc

little crystals of AgNO3 after sitting in the dessicator for a month, most of it is still not dry!
but this looks just like coral

Hey all, I'm guessing this would be the thread to ask this question. I'm looking for some compounds/ crystals to display in my apartment. Obviously
they should have to be non toxic and have a "shelf" . If they could be placed
under a UV lamp that would also be a plus. I'm open to any ideas and would hopefully be able to fairly easily prepare them. Thanks for any ideas!

Wrong place to ask your question. Regardless, they're called mineral specimens. Try eBay.

Well I don't want to just buy a mineral... if I wanted to do that I wouldn't need to ask haha, I'm more interested in growing something on my own that
has a shelf life and is non toxic and preferably not out of some crystal growing kit

CuSO4, normal alum, NaCl, I found Sr(NO3(2 makes nice crystals, especially with impurities you can get an impure crystal inside a pure one, looks
really cool

Since this topic looks like it's dead... Here is a picture from an elecrochemical reaction what we've made, or we could say that we've tried....
In the cell there was a tungstern cathode (that spiral at the bottom) and a platinum anode (the net in the center). The result was a black gunk.

Kristof, you really keep this post alive!
That is a nice container with the built in cooling! what exactly were you electrolizing?

This is the most Beautiful Reaction I have seen so far in my history experimenting with chemistry. I was going to post only a picture but the video from my YouTube
channel is just amazing. It reminds me of a view of earth from space. Be sure to adjust the video player setting to 720p so you get the full HD
experience.
Please let me know what you think and thank you to the people who commented and subscribed.

A 30 liter keg with a snorkel and some methanol inside - a simple demonstration using a water bath for cooling.

Well, not to down it but I've seen that movement several times in alcohol/water/lipid solutions, but the blue contrast with the white
really makes it a masterpiece in my eyes. Also since it is a vid I really love it
Any sufficiently advanced technology is indistinguishable from magic.

So that effect was happening at room temperature? That's neat that you'd see that conevection-like movement without any heating.

Ahhhhhhh! Fanboy time. I love lab photo! Following it for ages before I got an account here. Look it's mr homescientist repling to chemcam...

Well I got a pretty one, but it's carcinogenic...  keep it in a Perspex box? http://www.sciencemadness.org/talk/viewthread.php?tid=23905 (I liked it too)

Yes, room temperature. It was 72F in my house on my desk. There was definitely no additional heating but the motion was activated by the vibrations of
me walking up to it. You can tell near the end of the video that it is becoming weaker and weaker, because I am standing still.
Finnnicus, I don't understand what you're trying to say, are you asking for a beautiful crystal that is non-toxic?

not really chemistry, but i found this insect collection that i bought at a yard sale a few yrs ago for 5 eur. somebody had borrowed them and
apparently neglected them as there is a little mold.

not totally chemistry related, but it is used as a catalyst support. I found some native asbestos last sunday while marching our cattle up the
mountain.
this is my attempt at showing it catch the sun. as I stepped over it on the mountain it lit up like white fire! the sun was higher in the sky then
and showed more than this shot.
this is a shot of indirect light inside. kinda just honey colored with darker blueish spots and grey specks.
at first I thought I had found a band of "tigers eye" but after looking closer it rubs off REALLY easy to furry little bits...
my uncle confirmed he knew of several places that it is in rock faces there. I am hoping to go back and find some larger veins. not that I want to
mess up my lungs by breaking it up, just for my rock collection.

You should put some naphtalene or camphor inside to sterilize it. It's a nice collection.

Yeah, there was something in it but it must have worn out. not aristobia sp. is all mouldy. what do you think, remove the mouldy bug and look around
for a replacement or leave it how it is?

I'd leave everything inside and just put a spoonful inside. They don't make the color go away, and they kill every bacteria, fungus and little critter
inside. I recommend camphor pill because that way you can keep it in your room, keep away moths and it smells rather nice.
