From the youtube description:
No ordinary alarm clock: the Princess and the Pea Alarm Clock (“PPAC”) leaves no room for snoozing, inflating a green “pea” between the mattress and box spring, making it impossible to stay in bed. In the tin can, a homemade Arduino-compatible board with clock and memory chips handles the alarm clock functions, and a power block under the night stand provides power and relays driving the sprinkler valve or other alarming alarm functions.
Grant is a notorious snooze button pusher, so this would be beyond perfect for him.
Too bad it looks purely home-made, and not marketable.
Yet.

One time, my mom threw cold water on me to try to get me out of bed. I actually pulled the sopping covers over my wet head, and went back to sleep.
