Calcium lactate 1g
Spoon (the rounder the spoon, the cleaner the sphere)
Split Chopsticks

Giant salmon roe is produced.

If you use a syringe or something similar to drip it down, it turns into small grains, or if you use a large ladle to make a large amount and put it in, you can make a big slime-like pudding object.

*Sodium alginate and calcium lactate are available in cosmetic and edible forms, and we recommend using the edible form.
