Mars opener
this opener will open Mars for us...
It was created (designed by Armin Stachiewicz) in a new way (I keep checking it out, please give me feedback if you know any similar solution).
The method is extremely cheap. You can easily repeat entire process in your own garage or even in kitchen...
