  Wash and dry the glass jar. It does not need to be new, but it must be clean.
  
  
• 2). Pour 6 oz. of water into the glass jar and add 1 tsp. of the gel crystals. Stir the crystals several times in the jar with the non-metal spoon.
  
  
• 3). Add the food coloring. One to two drops may be used for a lighter color and subsequent drops can be added until the desired color is achieved. Stir the food coloring several times in the jar with the non-metal spoon. (Ref. 2)
  
  
• 4). Add 1 tsp. of the fragrance oil and stir with the non-metal spoon until thoroughly mixed. If a heavier fragrance is desired, an extra teaspoon may be added.
  
  
• 5). Allow the Smelly Jelly to sit, uncovered, for approximately one hour so the gel crystals can absorb the liquid. A lid may be placed on the jar after an hour if the Smelly Jelly is a gift or the jar may be used immediately by leaving it uncovered.
