How do you add caffeine to lemonade?

[littlehomie]

Heyyaaa! I'm all about experimenting these days. I have thought of adding some kick of caffeine to my lemonade recipe. Has anyone tried this before? Did it turn out okay? I'm open to your suggestions and advice. Let's brainstorm.

I think mixing in some green tea could add a nice caffeine boost to your lemonade. It's refreshing and gives a subtle kick!
