Have the lemon juice ready.
Squeeze all the juice you can out of the blueberries. There won't be much.
Strain both the lemon juice and the blueberry juice through a strainer for a clear juice.
Heat the cup of water to boil in a small saucepan. Add the sugar and stir to dissolve.
Let cool a bit.
In a large bowl add the lemon and blueberry juice mixture, sugar water and 2 cups cold water.
Let cool before filling your Popsicle molds.
Fill up the mold with the juice.
Freeze at least 6 hours.
