Greeting Sir, I made crackling star with lead tetraoxide some time it explodes and some time it brun and red like iron red in fire kindly inform what is the problem thanks
Why do you need that? I don't understand the point of a double motor. Just because you can or why would you build something like that? It's still cool though.
out of curiosity, why 2 motors, and why nozzleless? why not a single bigger, probably nozzled, motor? and less relevant because, well, they're firework motors, but why not try some higher performance stuff like sugar motors or even APCP? i mean's don't get me wrong, they're great, i'm just curious to the motor choices because i'm a firework nerd and a rocketry nerd.
Oh, there are lots of ways to skin the cat. These rocket motors just build on the size I like to make, simple BP propellant, and the skills I already have.
Good work but those bursting charges are very weak. I build the shells from 4-12" without flash booster and also without black powder based hulls. Seems you only miss good powerful burst with very low density and without metal powders,perchlorate based
Beautiful from start to finish brother!! That still shot with multi color break is a stunner. The second break in purple was one of my favorites though. Thank you so much for sharing!!!
Isnt the part at 12:26 wrong if you do 2 scoops of 70 5 and 1 scoop of pure aluminum the ratio would be 37% aluminum and 62.3% potassium Isnt the stoichiometric ratio closer to 70 30? In that case you need to do 3 scoops of 70/5 and 1 scoop (25% of 4 scoops) of aluminum To have 70 30 which im pretty sure is closer to the right ratio Can somebody confirm this?
Actually I realize your mix is just slightly closer to the stoichiometric ratio of 34.2% aluminum and 65.8% perchlorate by mass but both would work fine I'm sure
it's beautiful. how do i get the first rocket effect? are the stars rolled or pressed? can I hot glue them to the paper hemisphere around the perimeter? is this the right way? it's beautifully smytry. Thank you :-)
Some folks are using corn starch from the grocery aisle. I think it's called corn flour in Europe. I've actually developed a method that I use now which doesn't include any binder. It's detailed in the website.
@@nedgorski wow I did not think you would have responded so quickly! I appreciate your help. Can I buy this binder from Chris at Fireworks? I appreciate your time Ned.
I know absolutely nothing about this. My guess is it wouldn't get off the ground, but what if you sequence the 2 motors where one fires after the other is almost done? Does more burn time mean more lift or is it all just thrust to weight ratio?
It wouldn't get far off the ground that way, Wayne. It requires the joint thrust from both motors burning simultaneously to get up to speed in that first 0.6 seconds.
Good Day Mr Gorski, I am making a batch of Tiger Tail stars for 3" shell but wondering if I should use my 5/16 plate or 3/8 plate? Will small star might brake with the burst charge? Thank you
