Spilled Coffee on My Boss's Laptop

So here I am at my first real job and I've already messed up. Today was supposed to be a big presentation meeting with my boss, and I brought along some coffee because mornings without caffeine are pretty rough for me. But when we got into the meeting room, I accidentally knocked over my cup while getting settled in, sending hot coffee all over my boss's brand new laptop. It sizzled and steam rose everywhere as everyone stared at me with wide eyes. My heart sank as I tried to clean it up quickly, but there was no way that poor machine would last another hour. I'm still wondering if they'll take me off the project or even fire me for this colossal screw-up. All day long, I've been trying not to think about what's going to happen next.
