Or...

  1. Several hopelessly addicted souls
  2. Several glass smoking implements
  3. A crack house (any apartment will do)
  4. Cocaine
  5. Some ammonium hydroxide (baking powder in a pinch)
  6. Some ethyl ether
Take one gram of cocaine and add it to a test tube containing an inch of water. Cap tube and shake until cocaine is dissolved. Add 5 drops of ammonium hydroxide and gently swirl to mix the solution. Add 1/2 inch ethyl ether to the tube and shake vigorously for one minute. Place tube upright for one minute or until seperation occurs. Once seperated take the top liquid and leave it on a clean dish. In about five minutes the ether will evaporate and you'll have pretty pure crack. This is where the hopelessly addicted souls come in...
