Improvise whistle from an aluminium can

Hi all,
few days ago I saw a clip on YouTube about a survival whistle done from an aluminium can...today I tryied to do the same

just a Vic Minichamp it's sufficient to do it

need firstly to obtain a rectangule about 8 cm x 4 cm

than you cut a strip 8 cm x 2 cm (more or less), and another strip 4 cm x 2 cm

fold the short strip around the long strip, nearly at the end, an fold the remainig part of the long strip

now, fold the free part of the longer strip around your finger, to obtain a curve, and open a little bit the shorter strip (for airflow)

need to obtain something like this


to obtain a sound (I ensure, pretty loud), you need to close the sides of the whistle with your fingers (thumb+index)


the whistle it's ready

I may ensure the sound it's pretty loud (also it's funny to make this little tool :-).
Ciao,
Alfredo
