This spooky season-themed video shows some incredibly easy do-it-yourself Halloween hacks. We love the sight of a jack-o'-lantern glowing on the front steps, but where does he even come from? If you guessed that the "o" might mean that Jack is Irish, you guessed right! It gets its name from the natural phenomenon "ignis fatuus" commonly called will-o'-the-wisp and refers to the strange light flickering over peat bogs. Children in Ireland and the Scottish Highlands in the 19th century are thought to be the first to carve jack-o'-lantern faces. The practice hit America by 1966, where it was associated with the harvest season and made appearances at Thanksgiving. It wasn't until the mid 19th century that they became the emblem of Halloween.
