Prototypes:

There are people out there just waiting to help you create and configure your invention into a working minimal viable product.

A breathing entity .

If you need engineering, artistry, or tech driven help, there are people for you waiting to assist. A chemist understands material science and what your creation is made out of . There are engineers who have 3-D printers, who can make anything from a small size of a toothpick , to something as big as a treadmill.

Prototypes are strongly recommended, so you can determine in the future if anything needs to be reconfigured.
