I am guessing that Naptolene fits in here. I dreamt that I took a thick cored piece of wrapping paper tube 4-5" long, capped the end, put 1/2" of P, 2" of BP/nap mix, and 2-3" of Nap. When it went off it just launched the Nap up with no flames at all...any critique on what went wrong.

get a bigger diameter tube. the Nap was not exposed to the burning BP long enough to lite. (obviously this is the case, i just like stating the obvoius ) i would try a bigger diameter tube and possibly a slower burning BP. how wide is the tube now? and how fast is the bp?

I lightly packed it with the end of a test tub, would that mess it up? Do I want it loose, packed lightly, or rammed?

Adding a cap as showing in Alen's diagram (circle of card glued over the top) would help the nap ignite as the hot gasses from the BP which push through the nap to burst the top.

yes, slight confinement is a must. but not too much, we dont want it to explode.if you pack the nap hard, make sure you have a strong endcap glued very well. or else it just rockets the tube. this happened to me about 3 minuites ago..that was a first

I only had a piece of cellephane on the end that time. I'll try again with more confinement.

From the diagram it looks like there is only a piece of wadded up toilet tissue in the end. Do I need a loose cardboard plug after that also?
Off topic: Is there a way to kill these annoyiny advertisements? Everytime I start to type one pops up...ticking me off big time.

tape some Al foil over the top and poke a needle size hole in the center so it holds the gases up a little and when they try to escape, they go through the pinhole and rip the foil evenly.

i once saw someone i didn't know try this and it didn't work either, he tried many methods, but could not get the nap to light, it probably was that the napthalene had some othere stuff in it because it was mothballs...maybe that was the problem for you, where did you get your nap from?

Some modern mothballs will not work at all. Check that they contain napthalene.
Film canisters work well for small ones.

Ingredients show 99.97% naphtolene...I think it might have been lack of confinement. I just had a piece of cellephane tape with lotsa small holes in it. I'll retry.

try and cap the device with something other than plastic wrap. try and use a glued on cardboard disk, anything that isa little heavier and more dense then the celiphane. (if sound is not a problem) if it is, than i would not step of the confinement that much.

Why not just use 40/80 BP/Nap in the whole thing, you wont get a plume of flame, rather a short flame-thrower like burst.
