Halloween is perhaps the one time of year you can safely prank strangers without getting punched in the face. Magician/actor Steve Valentine has five pranks you can pull on trick-or-treaters, party guests, the gang at the pub or your own kids using just stuff you've already got around the house. They're creepy without being too over the top or gross, and they don't require much practice or skill to pull off. Just please remember, after you cut a hole in the box, step two is putting your finger in the box. Your finger.
