Good day my fellow vape enthusiasts. 
Recently I had a friend build on my petri 24 Rta.
While doing the dry fire to break in the cotton, he pulled out a lighter and lit the cotton....
I'd just like to find out the reason for this if anybody could explain it would be highly appreciated.
(not sure if it was asked before)
Thanks
