Title: Tori's Pyrotechnics ;-)
Post by: Tori on 30 December 2011, 11:14:54 am
I know there are lovers of a good fire on here (You know who you are! :lol) So I thought I'd share my photos of last nights antics!
 
Fire spinning!

That's me in the middle!

cool. how'd you do that then?

I just pm'd you on facebook, but it's no secret really. It's basically plumbers steel wool (Highly flammable when rubbed with a 9v battery :lol) stuffed inside a metal cage (I use a cheap metal cooking whisk thing) Then a metal chain attaching the whisk, then spin spin spin!! The faster you go, the more oxygen etc, the more sparks. If you pack the wool less tight you get more sparks too. It's fun, but you must where a hoody an tuck your hair in a hat lol. I got a little singed!!

If you do't fancy getting incinerated, you can also do it with battery operated fairy lights. My fairy lights last night were nor very sucessful :( They were not bright enough really. I'm working on that ;-)

Lol! We all went out in black hoodies. The bridge was on a railway footpath. When some people came down the footpath, they turned around and walked back the other way. I think we probably looked like we were up to no good! A few folk did stop and express interest though, which was nice. We had a brief visit from the police, but nothing was said, they just watched for a bit!

Like most of my friends I was a keen amateur pyro as a kid. Unfortunately in those pre-internet days, finding information was harder than getting hold of the chemicals so my trial-and-error approach to firework making was somewhat hazardous. Inevitably, at the age of 13 things went a bit wrong and what was planned as a pretty fountain made an impressive bang instead. The police were probably a lot harder on the chemist I grassed up as the source of my supplies than on me. These days a similar sized explosion would probably have got us all shot as terrorists. :lol

That's it! ;-) If you just spin the sparks are going away from you. In tunnels, it's raining down on you, so be careful if you try it. And like it says, don't try it at home, try it at somebody elses :lol:lol

i used to do that as a kid. the key is not to buy the steel wool that has soap in it.  :rollin we used to used to wrap it around a wire coat hanger and spin it around. wasn't as fancy as your one

I like that... I wonder if the steel wool had some copper swarf in it ...Hmmmmmmm I feel an experiment looming
Title: Re: Tori's Pyrotechnics ;-)
Post by: Tori on 31 December 2011, 07:48:55 pm
Thanks :) I don't know what copper swarf is? Or how it'd burn? Does anything burn blue? That would be quite impressive!
Title: Re: Tori's Pyrotechnics ;-)
Post by: Fazerider on 31 December 2011, 08:08:11 pm
Yes, copper (or copper salts) can give blue or green colours in firework compositions, but it might be hard to get copper swarf to burn in air... I don't think it gives off enough heat to maintain the reaction without a more concentrated source of oxygen. Usually it's used as an additive to a mixture which provides the high temperature rather than being the active reducing agent.

If only you could play a musical instrument while doing this,  :eek you could be the next Rammstein. :D

Apparently copper chloride is needed but it's naarsty stuff giving off noxious fumes when burnt.
Title: Re: Tori's Pyrotechnics ;-)
Post by: Tori on 02 January 2012, 02:13:49 pm
:lol:lol

I'm having another go at this on friday, but could do with some ideas for some 'non noxious' additives! ;-) I'm thinking of adding my fairy lights to make some more colours, but they may get a bit burnt. Any ideas appreciated! :)
Title: Re: Tori's Pyrotechnics ;-)
Post by: Fazerider on 02 January 2012, 03:31:05 pm

You could try including aluminium swarf or filings which might give some bright white sparks to contrast with the yellowish ones from the steel wool.

What about foil? Lol I'm not sure where to find the other things!

Love the photos Tori - and I bet this gets recreated at the next spring meet

Post by: GringoRojo on 02 January 2012, 04:31:40 pm
add sparklers?
Title: Re: Tori's Pyrotechnics ;-)
Post by: Tori on 02 January 2012, 05:24:00 pm
Thanks :) Sparklers....oooo can you get ones that burn different colours then?

You can...  they smell terrible. :lol
Also, the faster you wave sparklers around the dimmer they get. (They supply their own oxygen so the rapid movement only has a cooling effect.)

Paul, shall I bring PROPER stuff with me then?
I think it sounds similar to Termite, but with an "H" somewhere...

Tori, table salt should give an orange tint, try low sodium salt in it for a nice purple colour.
:D

Post by: Robbie8666 on 06 January 2012, 01:44:25 pm
want to try this but how do you get ignition? I know you have said a 9v Battery, do you leave it in or just use it as a scource of ignition?
 
how long does it take to light?
Title: Re: Tori's Pyrotechnics ;-)
Post by: His Dudeness on 06 January 2012, 05:44:10 pm
they light with a naked flame so a normal lighter would do
Title: Re: Tori's Pyrotechnics ;-)
Post by: Tori on 07 January 2012, 10:48:08 am
If you rub a 9v battery on wool it ignites it, or just use a lighter. Fine grade wire wool burns best. Don't buy the pads as they're too tightly packed and don't ignite or burn so well.

I was out again last night, so I'll have some more pics up later :)

Not such great results last night...the rest of my pics are here:

Looks like a fun evening. :)
Did you try any additives for a different effect? The sparks in one pic look a different colour.
Title: Re: Tori's Pyrotechnics ;-)
Post by: Tori on 07 January 2012, 02:17:56 pm
No I didn't this time. To be honest it was so cold and windy I didn't hang about on that jetty long. Plus the locals get a bit antsy lol. Wooden boats etc...
The colours are just post processing :) It is great fun!

I am interested as to what 'Termithe' does  :rollin
Title: Re: Tori's Pyrotechnics ;-)
Post by: Fazerider on 08 January 2012, 01:11:21 pm
I was wondering about rigging a canister of steel wool to a bike, forward motion providing the airflow for good combustion rather than whirling it round manually, though some care would be needed to ensure you didn't set fire to the bike or yourself. With electric ignition from a switch on the handlebars it could result in a good photo either from a distant viewpoint or from a car alongside... should look like the bike is rocket propelled. :lol
Not that I'm suggesting this should be attempted on public roads of course. ;)
