I used to use my bedroom window as a fume "cupboard". It slid vertically and there was a garage roof just outside.

Okay, that won't help many people.

While on the topic, though, goggles aren't a bad idea when working with stuff that might make nasty gases. Not always the first thing you'd think about but if things start to go wrong, it helps if your eyes aren't stinging and watering like mad. You can hold your breath but shutting your eyes is not good.

oh dont worry I had much worst in the middle of the night I antecedently light off a H 134 rocket propellant grain mad from AP and HTPS the cloud of smoke was so thick I couldn't breath and I tried everything eventually I gave up and told my parents and I caint do rocketry anymore but I got a huge fan and in the morning it was clear. I was lucky to make it out with my life those things burn extramly hot and go allover the place. but seriously go see a doctor.

Erm, is it just me or is there a real problem with the idea of white smoke being carbon which is black?
Anyway, presumably your parents have noticed you coughing. Tell them you think you ought to see the doctor about it. I don't know how old you are but if you can get ot the doc's on your own then you don't really need to tell your parents (I think it would be a good idea to tell them anyway, but if you don't think so I guess that's your choice) On the other hand you probably should tell the doctor.

Well, rainbows, which are all pretty colours, are made of water, which is totally see-thru. I've also seen white smoke when playing with carbon arcs. It may be some other ingredient in the pencil "lead" rather than the carbon. Or it may be something else you burnt later on.

But whatever colour the smoke is, it's still probably a good idea to see a doctor about it. And a note to our other members: If you're going to burn things with electrical discharges, don't breathe in the smoke. Open the windows or something. Better still, just don't burn stuff for the sake of it! I'm getting too old for this.

"It may be some other ingredient in the pencil "lead" rather than the carbon." They were filled up with wax whenever I tried to use them as electrodes. but as you say, Check out the doctor and vice versa.

So the vote is to see a doctor... Well I guess that is a wise thing to do, better be safe than sorry.

I like burning and doing things for the sake of it, unless 13 too old?

Seeing the doctor sounds like a good idea.

Burning things for the sake of it etc can be great fun, just look after yourself while you do it. When I was young I didnâ€™t worry about my health if I was doing something that interested me. Looking back I wish somebody had told me to make chimneys or extractors rather than breath smoke.

So did I - especially exploring new oxidisers to mix.

I'm glad I did. It's educational (unless you're just a pure pyro). Looking back, I also did stuff I'd never do again - I can't believe I did it the first time. So, you either make the effort to learn safety or nature teaches you the hard way. In many things, nature doesn't give you second chances.

The wax in pencil lead will generate quite a lot of thick white smoke when it is heated the first time. I have heard about pencil lead without wax but I have never seen it.

I have never gotten a significant amount of smoke from pencil lead after the wax has evaporated, even when glowing white hot.

If anyone wants to try it, make sure you wear goggles or stand well back because pencil lead and other types of graphite can explode when heated. I have had one piece of pencil lead explode violently. Moisture can enter through cracks in the graphite and when you heat it to 1100 deg C you have potential bomb.

Hehe, no I'm not a pyro... HV is more fun!
Another dumb thing I did was to launch a thick slab of metal that weighed about 2kg into the air, I waited, and waited, looked up, moved a little to one side then it narrowly missed my arm and stuck into the ground a few inches away from me. Hmmmm I wonder what had happened if I didn't move and it would have hit me square on my head... Scary thoughts.

Yes I have had the graphite exploding, I dipped it in water then heated it, sending nice hot fragments around my room- I guess I was stupid to do that as well
