I really appreciate that, thank you. But, the reason I must stop this fall is because I'm heading off to college :cool:! I'd love to continue there but I doubt I'll find a professor who will help me, and bring lab chemicals into the dorms is kinda a no-no. I wont stop home chemistry and when I get a suitable lab will continue to film again but until then I have to take a break. :(

@Bot0nist lol I guess not, thanks everyone!

@Rogeryermaw yup, majoring in chem and probably a minor in computer engineering or computer science. I'm sure I'll be on SM all the time, no intention of leaving :D!

The internet chem store? Because if you have a local chem store that sells you all that that would sure be awesome!

It is local, but the trip back and forth takes about three to four hours...
But most of their items are way over priced, except glassware and ordinary chemicals and solvents.

Off Topic:

I'm sure you could find some profs that will help you out. My friend got some nice glassware and a few rare chemicals from school. I got free dry ice and liquid nitrogen!

Besides you should be bringing girls back to your dorm instead, hehe

I took comp eng, I recommend against this as a minor unless you jut want the degree so you can get hired as a programmer. Comp sci is worse.

You learn way more about programming just be doing it for fun. For school its just aggravating and they don't teach you anything or how to do it properly.

Thanks for the advice, all of it ;)

I am planning on minoring in comp sci as computers are my second interest. I've worked as an IT person for my high school and enjoyed that but I can imagine that wont be the focus of those classes at all. I guess I'll see how it goes.

I'm not much of a programmer but I'm learning python right now and its a lot of fun.

Finally had to break down and buy some sulfur powder from an actual chemical supplier due to the fact that I wasn't able to find any locally... Anywhere!? Pharmacies all tell me they "used" to carry those types of things but jot anymore... Garden supply stores don't have it either... But 13$ for 500g of ACS grade isn't bad I guess...

Also waiting on 1lb of calcium carbide from eBay!(13$+13$ shipping... Not bad!) I've been wanting some of that stuff for years! ;) can't wait to try dehydrogenating it in chlorine and perhaps trying out some acetylide syntheses!

excellent grab on the CaC<sub>2</sub>. i've been wanting some for a while but the supplier i use charges hazmat fee for shipping it. hope the seller was following regs.

<a href="http://www.sciencemadness.org/talk/viewthread.php?tid=17088" onclick="window.open(this.href); return false;">this thread has an example of how improper shipping can lead to a world of trouble.</a>

I was also surprised at how cheap shipping was... But looking at all the positive feedback on eBay seems to indicate that customers are all receiving their items, lots of feedback also from Canadian customers like myself and none report issues so... Fingers crossed! It's coming from Czech republic, I'll post a pic when it arrives :)

Yea its that very one. $565 new ouch!

It has some weird packing material, like loops of fiberglass string. Might poke it out and use glass beads instead.

FINALLY it has arrived... I thought it surely got caught at customs but low and behold two weeks later I received the Carbide... packaged in a yellow envelope and triple bagged inside. The shipper labelled it as "stones" on the customs sticker...Hence the cheap shipping through normal airmail for 13$ :P

The smell is strange and not quite enjoyable, I have never had the "pleasure" of experiencing the scent of calcium carbide. Fizzes like crazy and sure as heck gives off Acetylene, overall... very happy! :D

As promised, I took a picture of what it looks like.

Pure acetylene is odorless. What you are smelling is toxic impurities such as arsine, phosphine, hydrogen sulfide, and maybe some hydrogen selenide.

Try not to sniff it too much...

I actually meant the chunks themselves, I knew the acetylene would be contaminated with that stuff but the stones on their own also have a pretty potent smell... I opened the bag and I certainly wasn't prepared for a blast of air that smelled like... that.

Thanks for the warning though :P

A few interesting solvents, salts and metals...

1lb Hg
100 g Se pieces
Resorcinol
Na2S
NaF
NH4HF2
NaNO2
DCM
Trichloroethylene
Perchloroethylene
CS2
H3PO4 85%
Urea
GAA
CuSO4
Sr(NO3)2
Ethylenediamine 99.5%

Also got some glassware but am missing a 19/22 still head which I have tried ordering with Expediaglass for the first time so we shall see how that goes... their site is somewhat lacking in terms of information which makes me leery but it seems like other members have had okay experiences with them.
