Yep - I did look it up and I know that... I had that scare already. Didn't happen, TG.

It'd be fantastic if someone I could reach would be prepared to show me. Happy to trade skills if I can.

For time lapse photography I'd simply get a wire frame made to shape and tape visco to it. simple and easy and cheap, perfectly effective. also you could re visco the frame for a second shot if needed.

this is visco? could I wrap it around the wire like a coil?

Thanks for this, Arthur...

I just watched a visco video - it doesn't get that sparkly active... despite the backing music...

Plain Visco is not very interesting - it's just a fuse, but the crackling and flying fish versions have more sparks and colours. Could be a simple way forward for you...

When I dipped sparklers, I used long test tubes and a consistancy resembling thick custard. Needless to say the result was variable, and I think the effects fuse method would be a simpler and more reliable one. Flying fish fuse is quite fast burning as it is designed to self propell. You may want to get falling leaf fuse, which gives the same effect but is design to burn at a rate much closer to that of a normal sparkler.

Alternatively include a bit of metal powder in a slowed down blackmatch mix, then attach securely to a frame. This would get rid of the directionalness, as the sparks only go backwards out of effects fuse until the casing is burnt away, instead of the sphere of sparks surrounding a sparkler.

it all sounds possible and interesting. I'd really like to try some of these out. Any local groups I could visit? Happy to pay for membership if it's not too expensive. I'd rather get the help of someone who knows the materials in the first instance...

By the way, I'm happy to invest £20 in membership if that'd help. Expert advice all very useful. Meanwhile I'm going to buy a pack of indoor sparklers and try some things out.

Thanks all.

potassium nitrate/al powder flash can be mixed with recorcinol resin diluted in acetone about 3 -5 % sets solid is waterproof burns very bright white is cheap to produce doesnt self confine and rolled onto a wire frame like plasticine works very well evostick glue can be used instead of recorcinolas an air drying flare clay push visco in whilst soft as igniter dont put e match into it unless you want to make small mines in which case use a greased ice cube tray put the paste in with e matches in centre of each cube on firing small report and variable size ignited pieces fly in all directions

Can you still buy magic whips? The visco covered in crackle comp. If so they would be good I think.

[flynn]

I just checked and it doesn't look like it, unless they're called something else. Lots of youtube videos showing them bunged together to make bombs etc though...
