For example Jack o' Lantern:
The term "Jack O' Lantern" came from an Irish folk tale from the 18th century. Jack was an Irishman. He had tricked the Devil into climbing an apple tree. He then cut a Cross Symbol + in the tree trunk, thus trapping the Devil in the branches. At his death, he was unable to gain access to Heaven because he was a mean man. The Devil also having a long memory would not allow him into hell, instead he gave him a single piece of coal to light the darkness. Jack put it inside a hallow-out Pumpkin to keep it glowing longer.
Children continues to dress up today in various scary costumes and go around knocking houses doors to collect sweets. "Trick or Threat", and Pumpkins are used to make scary faces or people just empty the Pumpkin and put inside a candle.
