Kelly's Didgeridoo

My instrument is a didgeridoo.  I call it Kelly's didgeridoo.  I made it with a thing that you would put your golf clubs in, wax paper, rubber band, paint, and a paint brush.  The sound that it makes is wooooow, woooow, wooow, woooooow.  I make a sound by blowing into it.  My didgeridoo is in the woodwind family and that is my didgeridoo.
