Its a strange one this but I distinctly remember melting Airfix soldiers when I was a kid. Do you?
Why I did this I can now only speculate. Perhaps it was to remodel the bodies of some troops into new shapes. Maybe it was to change them so they fitted into vehicles. Maybe it was just to see what it was like burning them.
I suspect it was the latter as I can vividly recall being fascinated by the globs of flaming plastic dropping off the figures and hitting the tin foil sheet still burning. There was also a distinct sound like a jjjjjum as each blob fell.
Naturally there was also a smell, the cloying stink of lit plastic, which nowadays I really can't stand, especially when I'm outdoors.
Did you ever melt your Airfix or any other plastic figures?
