I got to thinking the other day...why can't they make an automated latte machine? I watch the Starbucks baristas actually foaming the milk, putting beans in the top to give two shots of coffee at the bottom, etc.
What if there was a machine that you put in the beans, the water, and the milk...and at the bottom, you'd get a perfectly made latte with foam at the top? No grinding, no foaming, no anything else. I bet it'd sell, too. The parts would have to be washable (especially the place for the milk), but otherwise, why can't they do this?
Just food (and a latte) for thought!
Have a great day!
