Here’s another one of those ideas that is so simple it’s amazing no one has come up with it before. It’s actually the work of a genius. It’s a plastic bottle with a special cap that holds 1.4 grams of a powder, like powdered green tea for instance. It’s released into the water below when it’s twisted open. So, you can mix fresh powdered drinks from a standalone bottle that you buy at the store.

I know, I know. In a way it’s pointless. Powder doesn’t need to be fresh and you can already buy your drinks premixed. But it’s just the kind of cool thing we would have seen Marty McFly do in the future.(Had the writers thought of it.) I see more of a future in using the caps with bottles you already reuse so you can have something on the go, when you need it.
