I've still got my carbide lamp from my spelunking days. Could use a new sealing gasket, but otherwise it should still work. Calcium carbide is still available if you actually want some. May be hard to find locally, but you can order it on amazon, among other places. No restrictions. The modern version of a gas bomb is dry ice and water in a bottle. Same effect and just as dangerous, without being flammable. Even easier to get...my local supermarket sells it. Also, it's not that hard to make, especially with the internet as a resource to tell you how. |

A 1973 film, Charley Varrick, starring Walter Matthau makes it very clear how much things have changed in the United States. Probably much of the western world is on a similar trajectory. In the film such things as chasing in and out of airports and buying dynamite at the hardware store are standard uncommented activities. Unthinkable today. There are many other examples of the huge cultural change that has occurred. |

I have some calcium carbide around here somewhere. I have an old carbide canon that is a miniature cast metal canon with a spark igniter on it. You put some water in a chamber and then drop in a pellet and wait a few seconds and then when you hit the sparker it makes an impressive bang. When I was in high school I had a chemistry teacher who made a big one that we got to set off at school. He was somewhat famous for explosions and fireballs, and always very popular with a very engaged class of students. |

Acetylene is some spooky stuff if mishandled, doubly so mixed with oxygen. My dad (who more or less behaves like the people in those old gory safety films) showed me how to fill balloons with an oxy acetylene torch when I was 8 or so. I remember it well, he filled up one to about 4 inches in diameter, tied it off, slipped it in an old Taco Bell bag (and somehow didn't blow us up with ESD), twisted it up, put it an small port-a-potty size disused tool shed scheduled for demolition, lit the "fuse", slammed the door shut, and ran (one of the few times I've seen him flat out run). It didn't turn it to shrapnel (purely by luck) but did pull out most nails about halfway. Even as a kid I recognized that as far too hazardous to mess around with, and that was before I learned just how sensitive the shit can be. |

As part of this function, we would send on the same plane, a bunch of aluminium road cases full of gear, including often, CRC cleaning fluid & RP7 lube, in "spraycans". These days, they would probably be a "no-no!" Our "Big Boss" was the "Broadcast Operations Manager" (BOM), &, as "internal politics" were always a thing, we were often to be found chatting animatedly, referring a lot to "the BOM"! I think that might cause a stir these days!! ;D |
