Un palloncino<\/span><\/p>\n

Procedimento:<\/strong>\u00a0<\/span>\u00a0\u00a0\u00a0<\/span><\/p>\n

1) Gonfiare il pi\u00f9 possibile il palloncino.<\/span><\/p>\n

2) Chiudere l\u2019imboccatura con le dita.<\/span><\/p>\n

3) Tirare il collo del palloncino lasciando uscire un costante flusso d\u2019aria.<\/span><\/p>\n

Cosa succede?<\/span><\/strong><\/p>\n

Il palloncino canta cambiando tono a seconda di come il collo viene tirato.<\/span><\/p>\n

Spiegazione scientifica: commento<\/span><\/strong><\/div>\n

L\u2019aria che gonfia il palloncino \u00e8 compressa nell\u2019involucro elastico: il collo del palloncino quando viene tirato vibra ed emette un suono tipo sirena.<\/span><\/p>\n

Se si cambia la tensione sul collo, si cambia anche la vibrazione e quindi il suono<\/span><\/p>\n

\u00a0<\/span><\/p>\n

English version<\/span><\/p>\n

The singing balloon<\/span><\/p>\n

Necessary<\/span><\/p>\n

1 balloon<\/span><\/p>\n

Procedure<\/span><\/p>\n

1 to blow up more possible the balloon<\/span><\/p>\n

2 to close the opening with the fingers<\/span><\/p>\n

3 to pull the neck of the balloon leaving to go out a constant air flow.<\/span><\/p>\n

What happen?<\/span><\/p>\n

The balloon sing changing the tone accordance with the way of to pull the neck.<\/span><\/p>\n

Why the balloon sing? Hypothesis<\/span><\/p>\n

1 Because the neck pulling do to pass not much air<\/span><\/p>\n

2 Because the neck is thin and when the air go out, is noisy because rubbing the plastic wall. The air then inflate the balloon is compressed in the elastic involucres. When the neck of the balloon is pull, it vibrate and sing a hooted. If you change the pulled, change the song too.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
