I told my best friend i'm bi-curious, what now?

So, I really like my best friend, and have done for ages.. I think i may even be falling for her. I basically told her the other week that I'm bi-curious and surprisingly she took it really well. How can I subtly let her know I might like her, without telling her. I'm scared of how she'd react if I told her so I just want to like give her hints and see how she responds, if she reacts badly then at least I know I still have a my best friend and our friendship wont be ruined unlike if I tell her. The obvious answer would be flirting but we flirt jokingly all the time.. So I'm not sure what I can do to show her how I feel without actually telling her?
