Rubbing together of two pieces of dry wood can produce a fire, with the careful use of the correct technique and kindling material, but it's a very tricky process. Enter the modern world of Rub Two Sticks Together.
This is a product that all campers etc can take with them, and simply consists of two sets of twigs contained in an oversized match-box.
The twigs have been appropriately treated with an A and B chemical in such a way as when one stick is rubbed vigorously rubbed against the other at a specific area, they erupt into flame, in exactly the same way as that of a match when struck against the side of its container box. The two sticks are then substantial enough to act as starter material for a larger fire. A and B sticks are different in appearance so that there is no possible confusion - ie one is straighter, and the other has more knobs on it than the other.
(somehow feel I posted this idea already, but could not find.... must have a clear out of old ideas sometime)-- xenzag, Dec 17 2015 You'll wet the bed https://www.youtube...watch?v=vWfS8_zqa14 [bhumphrys, Dec 19 2015] So, an oversized match?-- pocmloc, Dec 17 2015 Not quite..... as the box is not used as a striker.-- xenzag, Dec 17 2015 Something like two very large non-safety matches-- hippo, Dec 17 2015 yes.... except they're sticks, and need to be rubbed together, which is why the idea is called "Rub Two Sticks Together"-- xenzag, Dec 17 2015 What's the difference between a match, and a stick coated with friction igniter?-- pocmloc, Dec 17 2015 The very differences you have just described,-- guncandy, Dec 17 2015 The most effective way to use these would be to "find" the two twigs lying on the forest floor, and impress those around you with your fire-making skills.-- MaxwellBuchanan, Dec 17 2015 So what if you forget which stick is which? I mean, forget which is the one with knobs and which is the one which is bent?-- bhumphrys, Dec 18 2015 It doesn't matter if you forget, as long as you rub two different sticks together, you will get a fire.-- xenzag, Dec 18 2015 That's clever.-- bhumphrys, Dec 18 2015 See link, [Ian].-- bhumphrys, Dec 19 2015 The fire is cleverly hidden until needed.-- whatrock, Oct 19 2016 I just carry a small flask of phlogiston for such occasions, but pretty much any strong acid would do.-- not_morrison_rm, Oct 19 2016 Two small bottles of never ending sparks, nice. <....imagines nuclear fireflys>-- wjt, Oct 20 2016 random, halfbakery
