Making Black Powder
Make 13, themed around the concept of magic is on the newsstands!
It's another excellent issue and includes a PVC air cannon modification (by a different author) that is pretty interesting. It's called the boom-stick and is designed to maximize the noise.
I wrote three articles for this issue. The first is describes the DARPA urban challenge and the uber-makers that attended. While most of the competitors were big money corporate and academic types, there were a few entrants that really exemplified the ardent amatuer, and the skillful maker.
The second was the Maker Calendar and lists upcoming events of interest to those who make things.
The third article is about my foray into the world of gunpowder manufacture. I've received some great feedback from readers already -- it's something that a lot of people find interesting. In this article, I describe what I did to make home made black powder. I don't go into step by step directions for making the powder, but there is a good explanation of how to prepare your charcoal which is the really critical step in making the stuff. Everything else is less important.
