simple centrifuge for 2ml containers

It's just a **simple centrifuge** head to attach to a *DC motor* (powered with 9V).
I did simple tests and it works fairly well.

*Warning: do touch with your fingers or put in contact with objects while it's working, it hurt, and it can damage fragile and shredable materials.*

Also **don't forget** to put both tube and add rougthly the same amount of liquid in both, to equilibrate.

P.S: this also works as a fan, with airflow from the top to the sides.
