My son did a school science experiment on PJ cotton balls. He did plain, surface cote and fully saturated. The plain are gone in about 30 seconds, the surface coat last about 5 minutes and the fully saturated last about 7 minutes.

They are messy! <img src="/images/graemlins/tongue.gif" alt="" />

I get about 5-7 minutes from the Coghlan's Emergency Tinder. They have not melted in my H O T car here in Phoenix, in the summer. I am talking over 120 degrees in the car. The little bit of stickiness is a good thing. They will stay where you put them. You can pull one apart and put part of it on the end of a stick and use it as a big match to light your fire lay.
