It's almost Halloween time, kids! Here's a way to impress the youngsters, AND burn your neighborhood down:

Step 1: drink can of beer.
Step 2: rip the aluminum can in half, preferably using just your hands. A little blood to start your day never hurts.
Step 3: pour some white gas (Coleman fuel) into the bottom half of the can, maybe 1 inch or so
Step 4: put the can into the pumpkin
Step 5: light a match, and drop it into the can from about a foot up
Step 6 (optional): withdraw your hand quickly, before the "whooph!" of the fuel lighting

Using a lighter is considered "Safety seventh", and not recommended... unless you have welding gloves and a welding jacket on, in which case you should go for it.

I stuck a pic from when I did this a few years ago into the tribe pics. It was a lot of fun and it is a great way to attract the kids to your house.
