OK - here's one for you science buffs out there. Just now, I was doing a bit of routine maintenance on my helmet (Cue fnarr et al) I cut off some of the excess strap last week and by the end of a week's commuting it had frayed a bit. Not fancying a bushy pom pom under my chin, I decided to glue the strands with super glue. Applying the glue to the strands in a sort of wiping fashion, I saw 'smoke' - real fumes coming from the glued area of the strap. What's all that about?
