Now THIS is cool. Do I need to get a bonfire permit before I try it?

Well, you do if you did it the way I did it, which involved accidentally setting my yard on fire ;-) but that was because I poured fuel on the outside of the pumpkin trying to see if it would improve the photo (no photo of that; was busy using the lid of the pumpkin to put out flames).

If you are sane about it and use a _small_ volume of methanol you won’t experience lawn pyrotechnics. I wouldn’t do it indoors, since it gives off more smoke than a candle and can set off a smoke detector (not usually, but it’s possible).

WHEEE! What fun! And I love how the aluminium foil acts as a reflector (as well as heat shield), just intensifying the effect!

This is so cool! We don`t do Halloween, but I`m thinking I could find another reason to create some funky flames. ;)
