Instruction
1
Take 5 tbsp. of fir needles, finely chop and pour 1 liter of water. Put on the fire until boiling, and then reduce the intensity of heat, and simmer for another 10 minutes. The resulting broth insist 12 hours in a thermos. After this time remove the tape from the essential oil formed on the surface, and strain the liquid through several layers of cheesecloth.

For uniform and slow heating of the bottom of the flask put under it a small asbestos sheet.
5
To the upper and lower fittings of the refrigerator connect the rubber hoses. The hose extending from the lower connection, connect with water tap. The hose from the upper nozzle move to the drain hole of the sink. The outlet of the refrigerator by means of allonzh connect with an empty flask in which to collect condensate.
6
Turn on the stove, then cold tap water. Under the heat action, the water with fir needles, boil, steam will be collected in the refrigerator to condense and become a liquid composed of essential oils and water.
