+		* Measure agar and put into a cup
+		* Pour water into the cup and stir it with a spoon.
+		* Boil for 2 minutes. I used the microwave. Stir　occasionally. A large cup is better to avoid spills.
+		* If there is evaporation, add water to make 50ml.
+		* Measure Glycerine, then pour into each cup. Stir it.
+		* Pour into some molds
