Hello everyone, I thought it would be fun to start a post that showcased everyone's homemade fireworks from this year. Here are a few of mine:

 

8 in a row Chalk salutes (sorry about the finger in the shot. Oops):

 

26 inch Saxon:

 

44 shot mini mine (fires very rapidly):

 

10 shot mine:

 

3 fountain cake:

 

Failed 26 inch saxon... I didn't double check the orientation of each driver as closely as I should have. Oops, still pretty though, and different than most:

 

Last but not least, my new and improved 'super zinger':

Blackmach: I'm glad you like them! It's quite a simple device. Make a paper tube 1 to 2 inch diameter, 2 or 3 wraps, glue the seem, fold and tape the bottom so you have a cup. Add powdered chalk, I used carpenters chalk line chalk, filling about half the cup. I tapped lightly to compact the chalk a bit, but I didn't tamp it or ram it. Take 1 small flash cracker (70:30 less than 1 gram), and place it on top of chalk, then add more chalk on top, then tape it closed with the fuse sticking out the top. Hang it from a line, light the fuse and stand back. I got my inspiration from a video I saw on Ned Gorski's youtube channel ( https://www.youtube.com/watch?v=srghPkVrFms ), and from various daytime fireworks I've seen.

Heres a 2 ounce Cored BP rocket with a 1.5" D1 glitter shell. It wasn't quite dark enough yet.

Heres a small aerial flash powder salute. I made 4 but only was able to film 1. This burst a bit too low.

I'm more of a year round pyrotechnician. I had a nice research experiment this morning.

It was quite successful, so much so that many neighbors came out (at 6:00am while it was still dark) to see what the explosion was.

I expected a very weak burst but it was very LOUD!

No pics, I lost my phone.
