Tube Organ

With the help of my carpenter father-in-law I just finished the Tube Organ, made of PVC piping. Gives a nice bass sound on the lower notes. I wanted it collapsible to it could be put together as part of the show - there's a fine line between what is collapsible and thus a shakier structure (remember that it needs to be banged on as a percussive instrument), or what is much more sturdy, but not as mobile. But I think we've found the happy medium. I suppose I should learn to use a tape measure more often - a lot of the work we did together was him redoing my sloppy work so that the thing would stand up straight...
