Wait 'til the feather duster drops (nice work on the loop pedals)
[youtube=http://youtu.be/Iu60MwpMiow&w=700] Aussie renaissance man Linsey Pollak plays "Mr Curly" (a contra bass clarinet made from garden hose) from his show "Passing Wind" as well as the feather duster clarinet.
On his website, he talks about how to make instruments. He's really quite good.
