In the video below I show you the device already assembled and ready to experiment with homemade cornstarch clay.

Here are some experiments I did with this homemade clay.

Conclusion:

• In this first version, I learned to make basic forms of pottery with this homemade clay made mainly with cornstarch;
• I discovered that hardness depends on the quality and consistency of the mixed materials;
• The idea of controlling the spin speed of the CD-rom was useful since sometimes we only require a slow spin and sometimes a fast spin;
• In the second version I have the idea to add and use a stepper motor and a servo motor in order to add details to the final product, for the moment I have only assembled these devices as shown in the image below.
