weknowpyro Posted April 23, 2006 Share Posted April 23, 2006 This post is on how to make a serpent. Firstly a serpent is a fountain that is shot up into the air from a mortar to give an awe inspiring effect. Firstly roll a tube(im using 1/2" id for my tube). Cut off two pieces off dowel and drill a nozzle in one of the pieces of dowel (I'm using a 3.5mm nozzle).Next make your Fountain mix,i'm using a simple mix of 8 parts bp and 2 parts AL powder.Next thing to do is to fill the tube with the fountain mix. Once done you then can ram it very gently.Once you have completed this you can then put in the nozzle and add fuse. I ussally use about 2cm of visco to set it off. Put it into the mortar, for this fountain i am using about 6g of lift to get good height. Picture of what it looks like when finished. Link to comment Share on other sites More sharing options...

Givat Posted April 23, 2006 Share Posted April 23, 2006 This fuel you use for the serpent makes a lot of gases and can make this serpent into a rocket, Isn't it dangerous if the serpent will ignite and fly like a rocket towards the ground?

weknowpyro Posted April 23, 2006 Author Share Posted April 23, 2006 They can do as i think mumbles said in 'aerial fountains' but in mine i do not core it and on mine it does not produce enough thrust to rocket off. Link to comment Share on other sites More sharing options...
dragonman586 Posted April 24, 2006 Share Posted April 24, 2006 Hello ever heard of end-burning rockets. Even if there is no core thrust is produced. If your hole is crooked enough or if there is a huge crack the thrust could be let out at an angle that will cause it to veer off course. You said 8 parts BP (milled or green mixed) because if it's milled. It could produce a lot of gasses and combined with the heat of the burning Al you could be making some serious pressure. Why don't you take one of these inserts and light it on the ground without burying it or anything while it's lying on it's side to see how much thrust it really has. Not to knock on you or anything its a really nice device, but I'm a little worried about the safety aspects. And one more thing.6g of lift for a 1/2" insert? Thats obnoxiously high.

weknowpyro Posted April 24, 2006 Author Share Posted April 24, 2006 True about the 6grams but my lift is poor as i do not press it. Yes it could rocket off but unless u can only get the serpent about 5 meters in the air i think u will be pretty safe because i have never had one of these flip when i have used them,so its unlikely to do it. I think with the serpent you take the same risk as if you were setting off a rocket. Link to comment Share on other sites More sharing options...
dragonman586 Posted April 25, 2006 Share Posted April 25, 2006 You don't need to press your lift to get some decent lift it takes in the neighborhood of 2g of granulated lift (moistend and passed through a screen) to get a 1/2" in the air. Heres an easy tutorial. http://geocities.com/mini_bielecki/how_to_make_pulverone.htm Link to comment Share on other sites More sharing options...
weknowpyro Posted April 25, 2006 Author Share Posted April 25, 2006 Cheers for that.

dragonman586 Posted April 25, 2006 Share Posted April 25, 2006 I understand what you are saying. Infact I have yet to follow a tutorial right down to every little detail. I always put my own spin on things. I'm just trying to save you some chems thats all. Link to comment Share on other sites More sharing options...
