The alarm goes off and you've only been asleep for three hours. You get out of bed and stumble toward the coffee pot for that dark roasted elixir. Even as you first inhale the bold aroma, the fog in your brain begins to lift. You add a little cream, or maybe you don't even bother, and you start sipping, and by the time you can see the bottom of your mug and you're reaching for a second pour, the day has come into focus. You're ready for anything.

But what actually happened in your brain?

This 20 ounce mug has the answers for you. When it first comes off the shelf, anxiously awaiting that first drop of rocket fuel, you'll see what your brain looks like in a world without caffeine. As you pour in your coffee, tea or hot cocoa and the mug starts to warm, the darkness evaporates and the design on the mug changes to depict the happy, alert, dopamine-infused brain imparted by the magical brew. 

Here's the short story on the science of what's happening:

As adenosine naturally builds up in the brain, it binds to the A1 receptor and keeps dopamine locked up. Caffeine works its magic by stealing adenosine's spot on the A1 receptor, which releases dopamine into the synaptic gap and makes you feel alert.
