Congrats, you didn't cheat if it worked <img src="images/graemlins/wink.gif" alt="" /> I've tried the typical PSK tinders like ranger band, tinder Quick ect. without much luck. you want anything that will take and grow a coal, char, tinder fungus ect. then the coal goes into a nest of fine tinder and you blow it to flame. That's the way almost all the primitive methods work.
By the way i consider this a secondary/bushcraft/ match extending tech., but it does have its uses, look at all the burning lens in PSK's and oldtime tinder boxes.
If you liked the coke can you should like the Saran Wrap method Walter has on his site now.
