How do you call that thing that is like binoculars but you see from down and see whats happening up?


In Spanish its called Monoscopio.
Those they use on submarines.
If you know how to make one of cardboard please tell me.
Even better if you know a web page that explains how.
Its to spy my brother. Thanks!!
