A cool video has emerged showing how to create an amazing Jack-o'-lantern party trick. <br /><br />The footage, shot on October 3 in Montreal, Canada, shows YouTuber VivaFrei cutting out a face on a pumpkin to create a Jack-o'-lantern. <br /><br />He then places the pieces back into the holes to make the pumpkin appear untouched. <br /><br />He finally fills it with butane and lights the gas on fire, making the pieces pop out of their slots.
