I originally had this idea a few years ago, during one of the Halloween contests. Unfortunately, due to time constraints, lack of effort, and lack of coconuts, I could not.
These little guys will last year after year (pumpkins are meant for eating, not rotting on your porch in two weeks). Just be sure to watch them so they don't catch fire (like most candles). Because, while he may look friendly, this b**** wants to burn down your house, and will sacrifice his life to do it. Crafty, evil little things.
Step 1: The Goods
1. A victim. (I have three)
2. A dremel. (for cutting)
3. Tea candles. (for lighting)
4. Sandpaper. (for sanding)
5. Something to scoop out coconut flesh, like a grapefruit spoon, knife, or chisel. Not pictured.
