SciFriday: Witches and Witchcraft (with Josh Peck and Steven Bancarz)

Witches are more popular in America than they've ever been. A recent survey found more people identify as Wiccan or pagan than there are members in some mainline Protestant Christian denominations. As part of our series leading up to Halloween, Josh Peck and Steven Bancarz, co-authors of 'The Second Coming of the New Age,' discuss the practice of sorcery and how it's even infiltrating mainstream Christian churches.
