Joining two bolts with one nut packed with caps could be great fun, especially if you mastered the art of tightening it just enough so they fly apart on impact.
I certainly remember them, and there was another type of 'cap gun' ammunition that were tiny red cups with powder in the middle, they were specific to toy revolvers I think and came in rings of six. Neither however, were anywhere near as good as breaking the heads off half a dozen matches, putting them down on the kerbstone and belting them with a hammer! Now that made a bang.
Last Tuesday I applied for a job in a sandwich factory.
Today I received an email to say the roll had been filled.
