Art Plastique.
La bouteille d'eau minérale en plastique devient un matériau
éolien à la mode. Ce banal objet de consommation,
ce vulgaire déchet domestique peut remplacer le noble bambou
pour singer une flute éolien. Il suffit, avec des ciseaux,
de découper une fente "sifflante" longitudinale
dans le corps de la bouteille. Plusieures dimensions de fente
sont possibles. Le son est bien moins pur (plus ou moins voilé
selon les types de fentes) relativement au chant du bambou. Par
contre, le temps de réalisation de la fente est infime
en comparaison, et le prix du matériau est
dérisoire.
The plastic bottle, this common object of consumption, this vulgar domestic waste, can replace the noble bamboo to ape an aeolian flute. It only takes, with a pair of scissors, to carve a longitudinal "whistling" slit within the body of the bottle. Several sizes of slit are possible. The sound is not as pure (more or less muffled depending on types of slits) as it is with the sound of bamboo. On the other hand, the time taken to carve the slits in plastic is negligible compared to carving bamboo, moreover, the cost of the material is absurdly low.

Fentes et Sons - Slits and soundUse only bottles with a smooth body, small or large size. The slits must have perfectly parallel edges, their lenght varying between 8 centimetres and almost the total height of the bottle, their width will vary between 5 and 17 millimetres. Use a variety of bottles to compose your aeolian flute. Dont' forget to close the bottle cap so that the sound may not escape.

Diverses fentes,
divers sons - Various slits, various sounds :-
A slit of 8 cm by 10 mm produces a deep sound except when the
wind picks-up and brings the sound one octave higher.
- A slit of 11 cm by 9 mm gives a medium sound, relatively clear
within a wide wind range as well in speed as in angle of attack.
- A slit of 20 cm by 6 mm gives a shrill whistle but requires
a very precise angle of attack of the wind.
- A slit of 16 cm by 17 mm will deliver a hoarse sound.

L'art du facteur d'orgue éolien en bouteilles plastiques
consiste à conjuguer l'épaisseur et donc la rigidité
des parois plastiques avec les dimensions des fentes, et à
mèler les diverses sonorités obtenues au sein d'un
même plastorgue. Dès que la bouteille siffle, les
parois se mettent à vibrer, en particulier, les fentes
qui constituent l'embouchure de cet instrument à vent.
The art of the wind organ factor using plastic bottles consists in pairing the thickness and therefore, the plastic wall rigidity with the size of the slits and alse to orchestrate the various resonances obtained within a given PlastOrgan. As soon as the bottle begins to sound, the walls of the bottles are subjected to vibrations, particularly where the slits constitute the mouthpiece of this windmusic instrument.
