@jsr,

Yeah I had seen that somewhere before; perhaps on my RSS feed. Impressive stuff.


I think for true stereoscopic vision, you will need 2 objectives, which wouldn't really fit that close together.

To the SF members who enjoy working with magic powders, you should watch this video to remind yourself why it is never advised to hold a large exploding firework in your hand while lighting the fuse.

WARNING: EXTREMELY GRAPHIC

As one member from APC put it, what an awful price to pay for one stupid mistake.

Big brother sees this stuff too often and steps in to protect us from ourselves. It is how we let big brother get so big.

Ouch, that's gonna leave a mark!

Jsefcik, find a pair of old head phones, and measure about 6 inches from the jack, and cut the wire, solder it in place of the speak on the alarm clock, then get a audio jack coupling and plug em up. Easy.

To a small extent, I know that feeling, the instant of fear, then the "why can't I feel my hand" fear. It's really not fun, fortunately I had a fairly minor injury, but the shockwave numbs your hand and you fear the worse.

Not nice, the video should be alongside this video as recommended watching for those partaking in such things,.


Slugs in a .410, can I ask why? It's expensive, and not that effective. A Mosin Nagant would be a better investment, you'll spend $100 on ,410 slugs just to sight in and hunt a bit.

I was playing with some homemade fireworks in the New Years,
Mate of mine made couple of mexican polumnas with reasonable amounts of flash powder (would of estimated around 7-8grams)
inside plastic bottles.

the report/shock waves from 20m+ was quite an experience compared to commercial pyrotechnics.
Won't be playing with those anytime soon though, nearly shat myself :P
