The Amazing Bosco would hypnotise his assistant and place her on
the tip of three swords. If you think that is enough, wait, he would
then proceed to remove the center sword and then the sword that is
holding the assistant's legs. Now she will be left floating on the tip of
one sword, piercing her head. A circular hoop is then passed through
her body to remove any doubts of any kind of support whatsoever.
Everything is restored back and the assistant comes off, none the worse.
