A kid decked out in Dracula's wardrobe, chanting "I vant to suck your blood" has got to have some fake blood somewhere on his or her costume. A spooky Halloween outfit isn't quite as scary without dribbles of fake blood to portray the carnage associated with the horror movie holiday. Fake blood is available at most costume shops, party supply stores and specialty Halloween stores. You can even whip up your own concoction with corn syrup and food coloring. Take care when using it, though, since it may stain.
