"You should not being able to remove the cap when hot without being scalded" is right and I'm not going back on myself, your the tool who jumps on threads with nothing constructive to say, at the end of the day I knew the answer to the problem YOU didn't whilst giving dangerous advise in the process.

I am not going to back down from this and the more attention it gets the more foolish I am going to make you look when more people start looking at this.
