What is the best fuse?

[Seymour]

Bundled sparklers underwater are very likely to burn very fast or explode, just like they do above the water. If they are coated this will slow the rate at which they burn or explode. If there is a gap between the sparklers the hot gasses get down there and start to roast everything.

 

What exactly are you trying to achieve? It sounds to me like you are trying to make an underwater sparkler b0mb, while at the same time trying not to make one. You just want a bright underwater flare?

 

Personally I'd keep the sparklers for giving to people at parties to wave around. Some people love this, and you get much bonus points, and you can get away with only bringing a few homemade rockets/shells/fountains and still having people feel like you contributed quite a lot.

Thanks for your reply.

I'm trying to find out if what you mentioned in your 2nd paragraph is possible. But I'm particularly concerned about the burn-rate being drastically altered.

I've made a few other posts.

 

My apologies if my inquiries seem somewhat clumsy....I'm a Newbie to this Forum.

So you want to make an under water sparkler bomb? Just about anything can burn under water that contains an oxidizer and has been water proofed. Aluminum and sulfur does not contain an oxidizer. And there are multiple things that can water proof. Just needs to not be water soluble. Plexiglass dissolved in acetone would probably work.

 

Being new to the forum doesn't make anything clumsy unless you are also new to speech. It seems you are just trying to hide what you are planning to do and are asking basic questions without just telling us what you are trying to accomplish. If you told us what you wanted to do then I'm sure someone could tell you how to do it. That's what it looks like at least.

reputable gun shops stock the best visco/cannon fuse heavily coated with lacquer making them almost impossible to extinguish it all depends on the seller..... you have possibly one of the worst kinds or maybe its not even visco...

I've seen numerous clips where large bundles of sparklers have been attached to aerosol cans. I was curious if this same idea would be possible, but underwater. I'm fairly certain it would work, however my #1 query is not the large bundle of sparklers...but the small bundle of sparklers (3-5 perhaps?) waterproofed & attached to the large bundle, as a type of starter fuse. If this small bundle of sparklers was coated in something like a waterproofing spray-rubber....would this affect the burn rate? Possibly speed it up?

 

Also, this idea used with one of those thick-walled propane cylinders used with small, portable welding torches?

[mike_au]

Just so we are 100% clear, you are talking about blowing up the propane cylinder right? not lighting sparklers with it? I apologise if that isn't what you are suggesting but that is certainly the impression I got from reading your post.

 

I'll make this short and relatively polite...

 

Go read the forum. The people here are practicing the art of making display pyrotechnics. We're not "blowing shit up". I am hoping that if you actually look into it a bit more that you will find that pyrotechnics is really what you are interested in, and that it is only because you haven't had the opportunity to be involved in it that you think that blowing up gas tanks with sparklers is the same thing (no judgement there, lots of people on this forum started out in the same situation). If that is the case, then welcome, hang around, read lots, and have fun. Pyro is, quite simply, awesome!

 

If however you look around and decide that coloured stars and perfectly timed breaks aren't for you and that "blowing shit up" is what you want, then kindly fuck off.

The time fuse is the simplyest solution. But i've used spolettes last year.
