No, I'm not talking about Harry Potter.. this is a witch's ball my sister gave me one year for my birthday.
A witch ball is a hollow sphere of plain or stained glass. Legend has it that they were hung in cottage windows in 18th century England to ward off evil spirits, negativity, witch's spells or ill fortune. Witch's Ball actually originated among cultures where witches were considered a blessing and these witches would usually "enchant" the balls to enhance their potency against evils. It is said that the beauty of the orbs attract negative spirits and their energy inside the glass Witch Ball.
