First, the magician takes two paper strings.
He makes one* into a loop ,putting his crossed thumbs through it .
His thumbs are bound with the loop*,and then tight* with the other
string* to cross it* by a spectator so that his thumbs should never move.
Secondly, his assistant holds a sword.
The magician puts his bound fingers close* to its blade* and passes* them through it,then pulling the fingers back, but neither* of the fingers nor the string is damaged
This trick* seems impossible in general unless either his fingers
or the strings are cut off. The magic showed a remarlable progress up to this level nearly one century ago.
