I like the idea of using regular cork that fit in the regular hose, no 
strainer, or wires to keep um captive. KISS

Are the corks just fishing cork?

     I worry about my child and the Internet all the time, even though 
she's too young to have logged on yet. Here's what I worry about. I 
worry that 10 or 15 years from now, she will come to me and say 'Daddy, 
where were you when they took freedom of the press away from the Internet?'
