maybe because of the lenght, possibly being used as swords by kids mucking about?

A little off topic, but a while back I made a giant sparkler. It burned for a whole 7 mins and 18 secs and contained a kilo of comp.

Quite possibly mate, BUT why would you withdraw something if it doesn't cause harm or injury in the first place? If they were held at arm's length in a gloved hand (as the instructions rightly state) they wouldn't cause problems would they? I would have kept them going until such time as problems arose or somebody objected to them, Trading Standards or the British Fireworks Association or the EIG.

scaremongering, you get it around the 5th, public think just because somethnig is bigger, it causes more damage.

Hehehe, bloody hell! A 1kg sparkler - that's bigger than some cat. 2 selection boxes! That really should dispel the (incorrect, IMHO) idea that sparklers are boring! That may even be largest sparkler ever made outside Asia (is it China or Japan that has the tradition of really giant sparklers?)

It was based on Potassium nitrate and Dextrose so it was quite cheap, and being cast was easy to make, but hygroscopicity reduces it's suitibility for storage for any time, so I usualy light them as soon as they are set. the effect ( a nice lilac flame ) is pretty but not too impressive, but the size, burntime and smoke quantity is!


Edit: This new quote function refuses to work for me, or rather I have too few computer skills to make it work, Could some computer competent person please explain? I click them and NOTHING hapens, which is very frustrating! Smileys don't work either. Thanks

its not the size of your sparkler that counts its how you use it... or was that something else ?

Erm, for me this merely is not a sparkler but a long stick of smoke composition
I think a sparkler should do one think: give of loads of sparks ;D And KNO3/sugar does not fulfull this citeria

It is based on KNDX, but I slow it down and add meterial for sparks, metal powders/ charcoal ect. But I prefer it without the sparks, as the sparks are not that impressive but I like the nice lilac flame.

Or you could just get some FeTi, add some pulverone (about 1:14 metal:BP) and charge it into a narrow tube. Add some touch paper and a stick and you have a "morning glory" like device.

Even a composition like this will make a respectable charcoal effect:

69 KNO3
20 C
11 S
