Pour enough vegetable oil in a cup/jar, chill over night. You can speed up this process using the freezer, for an H at least.

Place juice, water, sugar and agar-agar into a pot, stir

Bring to boil for a minute

Let stand for 5 mins (if you have a candy thermometer, it should read below 35 Celcius) – still warm but not scorching hot

Using a new syringe (I got mine from Walmart), make droplets of mixture into cold vegetable oil

Pour mixture out (reserve oil) and rinse with cold water
