Forget coffee. If you're still in dire need of a little morning boost, we guarantee that nothing will be quite as effective as the adrenaline rush you'll get from swimming for your life in this online drowning simulator. This is not for the faint of heart.

Feel What It's Like to Drown With This Terrifying Simulator

It all starts innocently enough; you, a Frenchman, are sailing the open seas with a buddy and nothing but blue skies. Then disaster strikes. You get knocked overboard, and your only hope for survival is to scroll like your (virtual) life depends on it. It's harder than it seems.

Head over here to try it out for yourself if you dare. We'll be staying on land for now. [A Trip Out to Sea via FastCo]
