  • First gather your ingredients: sugar, electric green food coloring, your favorite flavored oil, and the magic touch, vitamin B2 capsules to make them glow.
  • To make the candy you'll also need a stove, pot, candy thermometer, aluminum foil, quartz crystals to make the molds with, and rice to hold up the molds.
  • Before cooking, prepare your molds by covering the quartz crystals in aluminum foil, then carefully pulling the foil apart, leaving an impression.
