These little guys helped me make them and they had the funnest time!
The box doesn't have English instructions but fortunately the shopkeeper had it translated on a piece of paper. Unfortunately, I lost that piece of paper. Fortunately there's YouTube... this video here starting at 2:45
The box comes with a plastic white tray, where you do all the mixing, a mixing spoon, an eyedropper and sachets of powder.
We put the red powder in one and blue powder in the other. These will react with each other to form the red caviar balls.
Lastly the soy sauce! They all smell like bubblegum and candy.
