A Jack O'Lantern is a carved pumpkin, traditionally associated with the celebration of Halloween. People hollow out pumpkins, cut out shapes for eyes and mouths, and place a candle or light inside to create a glowing effect. The practice originated from an Irish myth about a man named Stingy Jack who tricked the devil and was doomed to wander the earth with only a carved turnip for light. In the United States, the Jack O'Lantern has become a popular symbol of Halloween festivities. Families often gather to carve pumpkins, displaying their creations on porches or in windows. This fun activity is enjoyed by people of all ages, contributing to the festive atmosphere of the holiday.
