Mario1 Posted August 28, 2009 Share Posted August 28, 2009 Ok. I just made my first fountain that produced a good effect. Heres the comp Potassium Nitrate 74Willow Charcoal 14Sulfur 12Aluminum flakes. Like a couple grams. I then used about 10-12 grams of the composition for the fountain. I used a 3/4 in ID tube that was 2 inches long. The nozzle was made with Fresh step kitty litter. It shot sparks about 6 feet high for about 5-6 seconds. Golden and silver sparks btw. My question is how do I made this fountain last longer? Say 10-30 seconds. Add baking soda? Thanks! Link to comment Share on other sites More sharing options...
Mumbles Posted August 28, 2009 Share Posted August 28, 2009 You can get a longer tube for one. Additionally, using a slower mix will be advantageous. More charcoal will extend the device, as well as adding additional sparks. Look here for some examples.http://members.shaw.ca/gryphon223/PFP/fountains.html Link to comment Share on other sites More sharing options...
Mario1 Posted August 29, 2009 Author Share Posted August 29, 2009 Thanks Mumbles. Another quick question- How do I make a crackling effect. Like when the sparks crackle and make noise. Thanks. Link to comment Share on other sites More sharing options...
Mumbles Posted August 29, 2009 Share Posted August 29, 2009 They're called dragon eggs. It's a special composition that would be added as microstars. Additionally Titanium and maybe coarse MgAl, make a crackling type of effect. Link to comment Share on other sites More sharing options...
Mario1 Posted August 29, 2009 Author Share Posted August 29, 2009 So adding more charcoal. Would a tiger tail comp work? I guess ill ty baking soda too. Link to comment Share on other sites More sharing options...
Mumbles Posted August 29, 2009 Share Posted August 29, 2009 You can try. It is a bit heavier on the charcoal than I was intending, but I've heard of it working before. You might want to try something more intermediate between tiger tail. and essentially meal. Something on the order of C6 or C8 might be good. They are on the above site I gave you if you go back to the beginning and get to the star category instead of fountains. There is no point in adding baking soda. Since you seem to have your mind set on it, I can't stop you. Just think about it this way. You can slow it down and add nothing to the effect (baking soda). Or you can slow it down, and add additional sparks and flame (charcoal). Now that I think of it, baking soda might make it more prone to explode by adding unneeded slag. Eh, I suppose excess charcoal would do the same thing to an extent. Link to comment Share on other sites More sharing options...
