G'day Little Robyn,

Of course, the Home Brew shop caps will still have the tenacious modern plastic seals. Unless you can effectively remove them, you won't have the traditional lagerphone sound ...

... well, some might say that's a good thing ...

but clearly, the value of such a handy source of rhythm sounds was quickly appreciated in our (Australian) past ... Some informants reported seeing bottle-top rattlers out in 'bush' areas as early as 1910 ... only 5 years after they were first applied, in the big cities, to Australian bottled drinks!

Regards,

Bob
