Turn on the stove burner to medium heat. Place the water and the blueberries in a saucepan over the burner.
When it boils remove from the heat and pour into a blender or Vitamix. Pulse for about 30 seconds until the blueberries are blended.
Add the gelatin (do not use collagen or it will not gel) and pulse again until gelatin is dissolved.
Place the worm molds (order here) on cookie sheets and pour the blueberry mixture into the molds.
Place in the refrigerator for an hour or until gelled. Remove from the molds and enjoy. Store in the refrigerator for up 5 days.
