Money:
put in a coin at the end where it is balanced on the thumb as counterweight...fold it in the note...


Radio:
Fold it flat, like the disappearing Birdcage...in the youtube video it looks so obvious that its not a real radio... its the same principle as the Bird cage which ist just folded flat and still on the table

In this particular Video it´s just made better by the performer ( always hidden behind the bill with one finger, kind of Practise, Practise, Practise ), in your first posted Video its very obvious...
