Napalm

It's pretty easy to make napalm, here's how.

Because I don't know what else to write about and it was between this and autoerotic asphyxiation.

Supplies you'll need:
Frozen orange juice concentrate (a subtle nod to fight club)
Gasoline
Styrofoam (packing peanuts recommended)
A little motor oil if you want.
An empty container (gas can, bucket, bottle, depends how much you plan to make)

Instructions:
Fill container about halfway with gasoline, start adding styrofoam, which will dissolve into the gasoline.  Keep feeding in the styrofoam packing peanuts, and you can stir or shake it to help them dissolve, until you get a nice thick sticky consistency like syrup.  If it gets too thick, stir in a splash of motor oil to thin it out a bit.  Then make yourself a glass of orange juice and test a small batch by lighting it and flinging a spoon-full of it at a wall or something.  It should stick to your target and burn slowly.  Good stuff.  Pretty sure it's not terribly illegal to make this stuff as long as you don't use it for anything illegal.  So have fun with it and stay out of trouble.
