I was looking in the internet for Whistles, since I want to have more. Here where I live (Brasilian Northeast region) it's not so easy to find a cheap whistle (the one i have cost me something about R$80,00 reais /$50,00 dollar/ £30,00 euros - Generation D + fare).
Really noobie move, I admit it. So I was looking in the internet the prices from US or Europe, but then i found this site:
http://www.ggwhistles.com/howto/
It teaches to make PVC Whistle.
Then I tought:
"It's cheap, mighty be 'fun' and according to the author of the site:
"Low technology, but high quality sound!
So I'm here to know your opinion on them.
Did someone already done those? How did it work out? Does it worth the time?
Or it's better to buy on Ebay?
