If you want to keep those pesky trick-or-treating kids away from your door this Halloween, you're going to need something pretty scary. This flame throwing Jack-o'-lantern looks like a good bet, as long as you don't get sued for setting some kid's Lady Gaga costume on fire.
The lantern uses a can of WD-40 as the fuel, with a tealight serving as the pilot flame to ignite the WD-40. You also need a whole MacGyver load of other bits and pieces to put it all together. When triggered, the lantern spits out a one second long jet of flame, that will certainly keep any sane person at bay.
Note: Dvice does NOT condone actually making a flame throwing Jack-o'-lantern. Anyone who actually does, is a complete idiot just asking for trouble. Just watch the video for the lulz and be entertained, it's more fun that maiming some innocent kid, or burning your house down.
