Yeah i cut it into pices (half) boiled it for 10 mins, put half wee (1cm) and half cabbage water (1cm) and watched what colour it went.
It went dark blue so we tried DH's just to see the comparison and it went proper bright pink!
I did some google searches and it is to do withthe PH in the urine and seems quite accurate!
