YOU CAN Make Your Own 4th of July Fireworks

Pt 101206

YOU CAN Make Your Own 4th of July Fireworks, Modern Mechanix – July, 1930

THIS month’s chemical section is dedicated to that noble and glorious purpose of celebrating the Fourth of July in noisy fashion—and with cannon crackers and colored fire that can safely be made in your own lab. However, before plunging into a pile of recipes and formulas it is necessary to warn you fellows to be extremely careful in preparing these mixtures. In themselves they will not blow up until brought into actual contact with fire or through extreme friction, but remember always that you are working with explosives—regardless of how mild they may be away from fire.

To overcome the dangers of friction it is well to mix your powders in small doses. A simple way is to put them on a sheet of fairly substantial paper and, by picking up two ends, rolling the powder back and forth as you raise and lower your hands alternately. But where you must use your pestle and mortar—watch out for friction!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. The organization of would-be fireworks makers somewhat pre-dates the organization of other “Makers” that is now getting all the publicity. There have been mail-order dealers specializing in chemicals, equipment, and BOOKS THAT GIVE MUCH BETTER ADVICE THAN WHAT YOU FIND ON THE INTERNET, and conventions rather similar to one-topic Maker Fairs. Homeland security hasn’t eliminated the fun yet, though they’ve done some damage.

    I’ll particularly recommend http://www.firefox-fx.com/ http://www.skylighter.com/ http://www.pgi.org/ http://www.fireworksnews.com/ http://www.westernpyro.org/

    Do be careful; even the long-time experts have a better-than-average chance of needing excellent medical insurance and/or a good lawyer.
