Materials:
10' of any size PVC pipe you might have or want to use. Pick whatever size you can fit in your car and you can afford!
2 "T" shaped connector pieces (that match the size of pipe you are using

1 cruciform connector, the type that has openings to join 4 pieces at the same time...looks like a "+" sign. (again in the size to match your pipe)
1 mess of curly ribbon like you'd use in wrapping birthday presents. Try other string like stuff, there isn't a specific size or type necessary.
1 pole to drive into the ground to mount your fabulous new air-powered noise maker.
1 hack saw
Thats all you need, if you find a sale, all the parts should run about $10
Step 1 Workshop

Step 2 Put it together

Step 3 Stringing your creation


For the side with the 2 sections of ribbon, it's easier to start in the middle instead of the end because you have two strings in it. This way you can adjust the tension from the ends and not have to worry about keeping track of 2 ribbons at the same time.
That's it. Drive your stake/post, stick your aeolian on it and be ready to mystify the neighbors and bask in the glory as people from near and far rush to your side and shower you with adulation!


Notes:
Wider ribbon will create a lower pitch. (Yes, narrower ribbon will sound higher, very good!)
Higher tension will create a higher pitch.
In higher winds, if you turn your aeolian so it's perpendicular to the wind the ribbons won't slap against the tube.
I've gotten many of my ideas for kites and Aeolians from Ciel Libre (Free Sky). You'll see a picture of the "lawnmower" rotor kite I've been trying to recreate from the picture.
I guess there's some mathematical stuff for tension and lengths of tube you can use to create a perfect chord or tones but I'm going out to fly a kite.....
Any questions or comments or humorous asides are welcome! I'll respond when I get back in, outside there's not a cloud in the sky, it's 75 degrees and the wind is a steady 14mph so it might be a while.
