Preserved Head How to shock friends with a cupboard full of human heads in jars.

Pickled pigs' feet in a jar is creepy enough. A cupboard full of preserved human heads is quite another thing. All it takes is a digital camera, a color printer and a little creativity. You can make shrunken heads, too. For friends with a smaller appetite for fright.

Wicked Washroom How to put on a horrifying sound and light show where it's least expected.

Scare friends where they'd never expect it: the bathroom. The brains of this prank is WeMo outlet switches and light switches you control from anywhere with a smartphone or tablet.

Skitter & Scare How to make inanimate objects come to life with a toy and an app.

Scaring friends is good fun. Showing them how ridiculous they look the moment you terrify them is even better. All it takes is a wireless home security camera, a printer and a good fright. The photos make nice gifts for friends. And perfectly embarrassing ones for foes.
