Re-enactor

Thought I'd see what people think of this..

At a re-enactment show I attended I was helping issue black powder and wireup pyros for the displays. All of the pyros consisted of small amounts (<25g) of BP ignited by fuse or electric match loose packed (in plastic cups or thin plastic bags) with loose plain flour on top- this was to simulate cannon hits. The show went without a hitch. However weks later discussing the event (online) with others who were present I foud myself and the team criticised on the basis that flour is lammable and that it was mere luck that none of the pyros caused injury.

The team in charge (who taught me how to prepare those pyros) had been trained by professionals and in non-battlefield use I have yet to encounter the flour igniting when used in this way (despite dozens of tests). However in case this comes up again I thought I'd see what you folks thought.

I think that there is a basis for what is said but only when compression/ larger amounts of BP are used. I can say that powdered milk certainly does do this (used when I did want a fireball effect!).

Hi guys, I'm trying to decide on a electric remote detonation system- I have been using e-matches for a while detonated by battery contact but want to move to the next level.

I need really to be able to detonate 10-15 charges spread over a medium sized area (battlefield simulations). Budget is fairly tight- up to £100. Any reccomendations?

I am trying to source 3" cardboard shells but having trouble finding a UK supplyer. Looking for approx 4mm thickness. Any ideas would be most welcome!
