HELP!!!!!!!!!!!!!!!!!!!!!! my lil man must make a musical instrument that vibrates for a parade on friday.  what can i do that would be cool and creative? ___________

Ok.  Make him a berimbau.  It's a Brazilian instrument like a bow and arrow that has a gourd as a resonating chamber.  Of course you don't need an actual gourd.  Here's what they look like...



So how would you make one?  

Get a branch or stick and some wire.  Bend the stick slightly and tie the wire to both ends basically making a bow and arrow.  Next take a plastic bow and drill or poke two holes in it.  Now run a string through the holes of the bow and around one end of the bow and arrow part.  Tie the sting in a loop shape as to compress the string slightly.  Now hit the string with a small stick. and use a rock to push against the string as you strike. It will change the pitch slightly.  You've got a berimbau.
