Slow burning incense cones.
Light the tip of the incense and allow the flame to burn for approximately 30 seconds. Extinguish the flame by gently blowing. The incense should produce a glowing red ember and a tendril of smoke, and will continue to burn on its own. Place the incense on a heatproof, non-flammable holder - the lid of the incense tin works great. Always burn incense in a well-ventilated room, away from flammable materials.
