How to make silicone and corn starch molds for plaster rocks

This video is the first part of a much longer video I previously made, where I demonstrated the whole process of making the silicone and corn starch mold and the casting of the plaster rock and the painting of the rock. This video is only for viewers that are interested in the mold making and the plaster casting process. I will soon post the video where I demonstrate only the part where I paint the plaster rock.
