Used them all the time back in the day. Light both ends? Ha! Rookie stuff. Break the stick in half and light all four ends. Will it burn your coat pocket? Darn right it will! I was once lightning a stick in the duck boat and dropped it when ducks were working. I can’t remember if I shot a duck, but I DO remember pulling that hot stick out of my smoldering coat pocket. Express 5’s we’re flying everywhere as they came out too. Those were the days.
