I looked around and could only find one example of titanium in a chlorate composition. The chlorate wasn't the main oxidizer in this star either. I mean, I don't see why you couldn't, but just be careful. I'd always be a bit uneasy adding something that will increase the friction sensitivity of a chlorate composition, but I think as long as you're careful it probably shouldn't be an issue. Personally, I would probably only use them in ball shells, or as comets in a can shell. There is much less possibility for friction that way.

 

If you decide not to want to do this, the effect can be approximated by using married or cavity comets/stars.

I broke a beaker by dropping a plastic 50cc syringe in it from 10cm height

Speaking of Ventsi making CuCl for campfires, does anyone know the quantity and quality of CuCl made from electrolysis with saltwater and copper wire? We were messing around with electricity today in physics, and we made a NaCl solution to transfer electricty across a table. Lo and behold, CuCl started forming. I assume that it was CuCl, considering the copper wire started to change colors, we got a bright green/yellow product, and the steel alligator clip started bubbling, and had a black crust on it once we were done.

I am thinking of attempting this, but I was just checking for opinions on the viability of this idea.

[50AE]

Better make copper chloride with copper, H2O2 and HCl. Electrolysis of copper wire in a NaCl solution will make a Na+ contaminated CuCl2.

[Ventsi]

Thats a really unreliable way to make CuCl, it will make it but there should be about half a dozen of other Cu+ slats formed, and as 50AE said, it will be horribly contaminated and useless for anything with the word blue in it.

 

HCl, Peroxide and Copper wire or HCl and CuCO3 are much better options.

Just ran through a field and forest to watch someone hand-fire a show. It was pretty good; the only downside was that all the shells broke with flash, and so I had spots all over my eyes, and so the shells weren't as good as they could have been. And now I have cuts all over my legs.

I also found that a good, cheap blue for fountains is made with 75KP:25Sugar+about 15PVC and 15CuO. Can't remember the exact ratios, but it works well, and is cheap.

Haha, there went 20mins of my life.... =D

Btw, Aluminum, there is no second "i".

 

 

 

[50AE]

Ventsi, I considered this: http://en.wikipedia.org/wiki/Aluminium#Present-day_spelling

 

Most countries use the spelling aluminium (with an i before -um). In the United States, this spelling is largely unknown, and the spelling aluminum predominates.[54][55] The Canadian Oxford Dictionary prefers aluminum, whereas the Australian Macquarie Dictionary prefers aluminium.

 

The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990, but three years later recognized aluminum as an acceptable variant. Hence their periodic table includes both.[56] IUPAC officially prefers the use of aluminium in its internal publications, although several IUPAC publications use the spelling aluminum.[57]

 

I chose aluminium with the "i".

[Mumbles]

Both variants also have different pronunciations.

Doesn't one go al-yew-min-ee-um, and the other goes uh-lew-mih-num? That's how I say them, but I could be wrong.

Does anyone here have fins? I've been thinking about getting some, but I'm not sure what kind to get. I would most likely be exploring my lake, and perhaps a few visits to the ocean for some body boarding. This says to me that I would need to get some regular-sized ones, and a pair of those samll ones used when body boarding. But, I don't feel like shelling out for two pairs. Any thoughts on which style to get?

[Ralph]

I use training fins (go to your local swimming club) you can walk in these they are fairly good for cruising around the beach and spear fishing but require a little more work

I'm reborn! Rolling cardboard tubes is sooo easy with a glass rod. The tube doesn't stick ot it, it slides off easily! I recommend it!

[Pretty green flame]

Why a glass rod? A polished metal rod works just as well and there's no fear of the rod fracturing.

[50AE]

My metal rodes are rusted steel, that's the problem.

[Mumbles]

Sandpaper.

[50AE]

Sandpaper.

 

I know, the rust was so much though that I realised I could save time using the glass rod.

[dagabu]

I use aluminum rod polished to a shine. No rust, no breaks.

[Pretty green flame]

Polished brass or alumininum, brass has an advantage in weight, helps a bit in pressing down the layers. An aluminium or brass rod will outlast most people.

[dagabu]

I found that some chems attached the brass rod and it has to be kept very clean. The Aluminum rod seems to be more forgiving to me.

Sweet baby Jesus!! How do I persuade some of my friends to not make a sparkler bomb? They were discussing at lunch how one of their brothers showed them how to make one, and I am just going, Please guys, Do Not Do This!! And they won't listen. I really don't want to see themselves blow up, and I am just worried what could happen, especially since some of them like to mix alcohol with their parties. These are the kind of people that like to make chlroine bombs and the like, and I usually distance myself from them when these things come around. But I really cannot let them make a sparkler bomb, but I can't directly stop them. Any suggestions on what to do?

Try to show them some pictures of burns and injuries from fireworks, claiming that it can potentially happen from a sparkler bomb.

Try to explain to them "why they shouldn't do it". Tell them what are the risks. Don't just say "Don't do this". There are people, like me, that hate receiving orders without explanation.

If after all this effort they still won't listen to you, let them learn the hard way.

[dagabu]

OK, truth time:

 

My eldest sons hand was severely burnt last summer when he was messing around with a handful of sparklers and they ignited in his hand. Thank God he can still use his hand!

 

He is now my spokesman for safety, and regretfully, that is the way it works some times. The Darwin Awards are there to teach us all a lesson I am afraid.

If they're good friends then try what 50AE said, show some pictures, if they're dumb enough to give it a go anyway, then I wouldn't lose any sleep over it. Let nature take it's course.
