Pumpkin lanterns, also known as jack-o'-lanterns, are carved pumpkins traditionally used as decorations during the Halloween season. They are typically made by hollowing out a pumpkin, cutting a face or design into its skin, and placing a light source, such as a candle or LED light, inside. The glowing light creates a spooky or festive atmosphere. The practice of making pumpkin lanterns originated from an Irish tradition involving turnips and was brought to America, where pumpkins became the preferred choice due to their size and availability. Today, pumpkin lanterns are a popular symbol of Halloween celebrations, often displayed on porches and in homes.
