Was just at a party with friends. Lots and lots of kids, and we were going to make a nice fire for mashmallows. There were about 9 kids between the ages of 3 and 6 and they all wanted to help make the fire. They all gathered bits of wood, sticks and such. Then I said "I'll light the fire with no matches or lighter" Using my tiny Boy Scouts of America keychain-sized fire starter, I struck several blasts of sparks off the firestarter with my leatherman into a handfull of straw and dry grass I placed in the middle of the pile. It lit within 10 seconds. The kids we happy to have the fire, but the dads all wanted to see the little keychain doo-dad. A fun night.
