Anyone who knows the good old Bengalhölzer or storm matches, also knows how much active ingredient sticks around on sticks. The ignition works well and the burning time to get there if you ignition and until the last faint smoke trails incurred expects - and of course only with no wind, mind you. The measure also under ideal conditions! I take those things for effects around Photos around dioramas, if there is to be a new snapshot in time "more alive". Otherwise, very funny eyecatcher at parties or so, because the smoke does not form a thick, lung excruciating swaths or neighbors could annoy. I imagine this fog sticks well before as "missiles" or other projectiles for RC modelers. They would only have to can ignite automatically ...
