Float the Vap0rb USB Ultrasonic Humidifier in a glass of water, plug it in to a USB port, and wait for the moisture to waft your way. Ultrasonic waves create steam safely and noiselessly. It even has an automatic turn-off feature, so you can safely go to sleep with it set to turn off automatically in a few hours when you're sound asleep.
