I found this neat little glitch yesterday in which you 
can make your sword invisible, so I decided to submit 
it to the best code web site around. 
This particular code requires the great fairy's sword that 
you get by reuniting the great fairy in the 4th level (the 
stone tower). What you do is you set your great fairy's sword 
to one of the C buttons, then you get it out. Now, with the 
sword still in your hands, you go up to a mailbox and offer it 
the sword and link will draw out a little great fary's sword,
 but the mailbox won't accept it, so when it declines your offer, 
link puts away the little sword and voila, an invisible great 
fairy's sword is in your hands. You know it's there because if 
you swing it, a little "air blade" will follow the sword swipe. 
Cool, huh?
