I don't know if anyoe has done this before, but I realised you
can set things alight through glass, without damaging the glass.
I did it at Wang Cars. I used the flame thing (whatever its
called) and aimed it at the window from outside. It didnt break
the glass, however the cars inside blew up!!! Before the cars
blew up there was no fire, so I wondered if it was caused by
heat, rather than fire???
