Step 1: In a pot, combine 4 grams (0.14 ounces) of agar powder, 150 milliliters (5.07 ounces) of water, and 60 grams (2.12 ounces) of granulated sugar. Heat the pot on the stove until the contents come to a boil, then turn off the heat.

Step 2: Stir 300 milliliters (10.14 ounces) of milk into the mixture. Place the mixture in the refrigerator to chill/harden into gelatin.

Step 3: In a separate pot, repeat Step 1.

Step 4: Stir an additional 300 milliliters (10.14 ounces) of water into the second pot, plus 20 milliliters (0.68 ounces) of shaved ice syrup, the more brightly colored the better. Once again, put the mixture in the fridge to cool and solidify.
