  1. He won't be laughing if the flame gets sucked back inside that can.

    1. Then it would go out.
      When you're looking at flammable gasses,instead of a fire triangle- heat, fuel and air- you also ad another leg that is fuel/air ratio.
      I don't know what's in the can, but natural gas will only burn when the fuel/air ratio is between about 4- 14% gas in air.
      Any more or less and you can light matches all day and nothing will happen.
