A jack-o'-lantern is a pumpkin whose top and stem have been carved off and inner membranes and seeds scooped out to leave
a hollow shell. Sections of a side are carved out to make a design, usually a face. It is possible, using thicker and thinner
sections cut with differing tools, to create surprisingly detailed and realistic designs. A light source (traditionally a
candle) is placed inside the pumpkin and the top is put back into place (often after a "chimney" is carved in the
lid in order to allow heat to escape). The light illuminates the design from the inside. The practice of carving jack-o'-lanterns
began in Ireland. Jack-o'-lanterns are generally made for Halloween, and were originally made from large turnips, beets and
rutabagas, before the introduction of the pumpkin from the Americas.
