How to buy good agar

1.  White powder is pure. Yellower is impure.
   
   
2. If it's transparent when set, it's of higher quality. If it's opaque/yellowish, there's other crap mixed in there.
   
   
3. Good agar sets tight, the noodles don't split away easily.
   
   
4. A well-trained dog will bark at pure agar jelly.
   
   
5. Demonic hellspawns will attack you if they find in in possession of 100% pure agar.
   
   
6. Like take a chill pill bud, it's not like you're going to be snorting these like a pound of coke yeah?
   
   
7. Buy the most expensive agar.
   
   
8. Super duper advanced ultra extreme agar is probably the purest. Unless you find tera-all-of-that agar.
   
   
9. Mix with coke. a. cola.
