My brother and I have been playing around and we took various spare parts around the garage and came up with this..... Sort of "bored in the garage" type fun.

Check out out the shower curtain rod reworked to be a straight pipe, (I keep telling him that he needs an expansion chamber on it). Loud as hell and surprisingly quick....
