Got bored and started looking around for smoke grenades and found . Not sure what to make of it yet. Apparently they converted some fused smoke grenades to an electric-ignited system, using a 9v battery to ignite. They claim that it's cool burning.
They're a little more pricey than regular firework smoke grenades. $5 a pop, unless you buy a case of 60 for $240 But I guess that beats paying $15 a pop for distress floating smoke (boating stuff) or even worse, $40 each for real military smoke.
The vids don't play well with Firefox, so you can download them directly . A couple of them show lighting the grenades with a lighter, so I'm not sure what that's all about. Also, the guy's heavy breathing is a little disturbing.
Anyone found a good site for maybe ordering expired distress floating smoke? I sometimes see them on eBay for $5 or $6, but it's rare.
