No problems if you have your Flintlock Musket on hand, or even the permanent smoking wick used with Matchlocks. LOL
But some good ideas here.
I was particularly taken with the zip lock bag trick in the vid.
Condies was always in the cupboard in my childhood days of the 1940's, for bathing feet in, along with Kero (use a few drops on sugar for sore throats & to put on cuts), blue bags for stings and the dreaded Castor oil for all internal problems. We had the wax matches that would strike by scraping across the cast iron stove top.
A mixture of Diesel & a (little) bit of petrol gets the fire off with a bang. They used to use that on the hot shower donkey fire at Daily Waters to alert the crowd that hot showers were on.
Condy's Crystals was included in WW2 vintage army snake bite kits. As for lighting fires without matches, our Senior Scout patrol won the Hoadley Hide competition mainly by being able to light a fire without matches. We used tinder and sparks from a rock. The tinder was a burnt hankey kept in a boot polish tin. Other patrols wasted hours attempting to do it by rubbing sticks. They used two hardwood sticks instead of a hardwood and softwood combination.
