if you have 2 (DEAD) lighters:
Hold Lighter 1 straight in your hand (12 on the clock) and hold down the flick part continuously (i'm sorry i don't know the name)
Hold lighter 2 horizontally in your hand (3 on the clock)
Make sure the flame part of the lighters are touching or very close then--
Begin flicking lighter 2 and a flame should come onto lighter 1. It will be small, but this should work!!!
I learned this while in Trinidad visiting my family for the summer, I hope it works!!! It has worked for me with lighters that have been dead for over a year lol!!
