How can the artistry of fireworks be made accessible to people with sight-loss? This interactive seminar explores multiple options. Drawing on my own experience in the pyrotechnical arts while becoming blind, I will present techniques for translating the visual appearance of fireworks into non-visual forms. Participants will learn how words, sounds, and touch can translate light across senses to make the movement and color of fireworks accessible without needing eyesight. I will provide examples from my own exploration of pyro-musical display design. On a broader level, this seminar also invites participants to consider how the low vision/blind community can be meaningfully included in public events featuring fireworks displays.

Death Defying Sanding Dust Fireballs Workshop

J-Line | Workshop

February 17, 2023, 1:00 PM – 4:00 PM

Presented by: The Jackalopes
$10 Max Attendance: 25

Have you ever wanted to find out how big of a fireball you can make with 5 gallons of extra fine sanding dust? Now is your chance to participate, collaborate and self-incriminate yourself with the madness of the J-line. This seminar will explore the technical details of the construction of a functional basic sawdust mine, sawdust mine with various pyro enhancements and finally how to pack a 55 gallon drum with black powder, 3” shells and sanding dust and live to tell about it! Participants will be able to assemble a 5 gallon sawdust mine and either shoot it at the conclusion of the seminar (if conditions allow) or return later in the dark hours and light up the night sky.

For those interested in doing one for the evening, during the seminar you will be assembling a rapid deployment kit consisting of lift, fuse, lift liner paper and prepared pyro inserts. We will finalize the assembly right before lift-off time. This is for safety concerns since we really don’t want a bunch of these things sitting around. Note: We can be a bit more adventurous with the ones getting lit during night time.

Participation limitations: There is only so much sanding dust we can transport to Havasu so we will only be able to make 25 mines.

Fee: $10 collected onsite

Safety: Eye protection required during seminar. Eye protection, hardhat and protective clothing for daylight shooting. Night time shooting – You will be in Jackalope Gulch so of course you will need all the usual B-line safety gear.

Presented by: Amanda Nixon
$20 Max Attendance: 16

Amanda, assisted by Gayle Bates from Fireworks and Stage Fx America and Charlie Holdaway from Holatron Wireless Firing Systems, will demonstrate and help each participant assemble six different kinds of Spark Producing Devices (SPDs) and Airburst. The almost lost art of rolling flash paper airburst capsules will be one of these. As shows now use premade airburst to save set up time, fewer technicians work with binary flash powders and the old techniques are not being passed down to the younger generation.

We will not be manufacturing flash powder but mixing binary kits.

Following completion of the six devices, Gayle and Charlie will assist the participants individually to set up their effects and fire them off with the Holatron System.

Do not show up without safety glasses, long sleeve cotton shirt and long cotton pants. You will be turned away. It is helpful to bring a sharp knife, scissors, and a small wire cutter. If you have an anti static mat wonderful, if not a piece of cardboard will help.

Firework shells greater than 24 inch are rarely launched in North America, and very little technical data is available regarding these exceptionally large shells. A team was established to explore and further develop construction and engineering techniques for the manufacture and safe launch of these exceptionally large shells to support an attempt for setting a potential world record.

Proper mortar design is required to provide a safe and predictable launch in proximity to the audience and support staff. Due to the payload size and potential hazards for failure, there are many engineering considerations for the design of the mortar.

This presentation reviews the process of internal and external ballistic calculations, the development of equipment for measuring internal pressure profiles, and the evaluation of resultant data for 48 inch shells. These techniques were then used for the extrapolation of internal pressure profiles for a 62 inch shell.

Building Multiple Rockets with One Set of Tooling

Tent 3 | Seminar

February 19, 2023, 1:00 PM – 2:30 PM

Presented by: Ben Smith

This seminar will detail the general construction of a variety of rockets using one set of tooling. Information detailing making fuels and basic shop safety guidelines will also be covered. Nozzled BP, nozzleless BP, whistle and strobe rocket construction will all be detailed. Though this class will use the FireSmith Super BP Core Burn tools, the basic techniques, fuels and safety guidelines are applicable to the construction of just about any type of rocket. A batch of benzoate whistle fuel will be made during this seminar. The making of strobe fuel will also be covered.

An Overview of the Mechanics of Pyrotechnic Strobe Compositions

Tent 1 | Seminar

February 19, 2023, 1:30 PM – 2:30 PM

Presented by: Kurt Medlin

In this presentation, Kurt will describe the burning mechanism behind pyrotechnic strobe light effects. Topics includes an explanation of the alternating ‘dark’ and ‘flash’ reactions that create the strobe effect and the roles of the chemical components in strobe compositions that create those two reactions.

Examples will be given for two families of strobe compositions commonly used in practice: ammonium perchlorate-based strobe compositions and nitrate-based strobe compositions.

The discussion will focus primarily on understanding the strobe mechanism itself, but will include special considerations and practical information on using strobe compositions in practice.

It’s what’s in the middle that counts!

Everyone that experiments with fireworks knows about fuels and oxidizers, what they do, and what can be added to improve or enhance the performance. But how many have tried to modify the quality of the presentation? An artist and a housepainter both use a brush, but the devil is in the details. A look at variations in formulas and containment will show that pyrotechnists have paid attention to control functions since the beginning. Military formulations are often finely tuned for specific purposes, and civilian products, while more oriented to profitability and ease of manufacture, still follow the same logic.

Did you know that road flares for use by the Colorado Highway Patrol are formulated differently than those used in Florida? What about a yellow star that looks good at sea level but is almost white in the desert or at low winter temperatures? These questions and many more will be discussed, and there may be more than one answer. It is impossible to cover a subject this big in a short review, but hopefully it will encourage open-minded research and new creative efforts.
