Juniper is a kind of pine tree. You collect some bark (pry off with your knife) and shred it to make a tinder bundle. Have some stiff stuff around the outside to hold it together and sprinkle fine stuff in the center to catch the spark. You place your ember in the center and then fold the bundle around the coal. Then you blow into the bundle to get a flame. My 11 year old son breathed in some of the smoke, so be careful.
