Story

"ELEC 220 is relocated next to the Moody Center of Arts at 9:25 AM?? How am I ever going to make it to class" - said an anonymous sophomore who was never to be seen at lecture again. Legend has it that he/she simply fell into a deep slumber and never woke up in time.

As you start the semester, you eagerly set your glorious goals of waking up at 7 AM in the morning for a run around the inner-loop, working out at the gym, showering, and then making it to your favorite 9:25 AM lecture.

Expectation

However, your routine often ends up looking like a chemistry experiment gone wrong: you fall out of your bed, realize that you woke up 10 minutes after the start of your first lecture, rush over to brush your teeth while stuffing a piece of servery bread in your mouth at the same time, and then embarrassingly walk into Ray's class 30 minutes late because the commute is just thatfar.

Reality

If you are a Rice undergraduate, you have felt this feeling: turning off your alarm at 8 AM in the morning and praying for an extra 10 minutes of sleep... only to wake up 3 hours later because once you fall asleep again... you aren't waking up again for a longggggg while.

But what if... your alarm can smartly detect whether you wokeupandstayedawake?

Imagine if your alarm is smart, the future of our times.

Allow us to present the USA (Un-Sleeping Alarm), which leverages cutting-edge motion-sensing technology, hilariously annoying beeper, and smart software to craft an uncomparable experience in waking up. USA senses the user's hand-waving gesture to be turned off, but, after a constant amount of time without registering the user's hand-motion, restarts itself and beeps once more in an attempt to both wake its user up and exert its dominance over the said user. If USA had its own voice, we imagine that its motto would be: "You can never get rid of me until you wake up."

Did we mention that this is also the best gift for your roommate who never wakes up before noon? You will scar them to no end that they will either (1) laugh hilariously and engage in a healthy wake-up habit or (2) terminate the roommate contract immediately and now you have a room all to yourself. Win-win.

Have to babysit one of your siblings or a friend's kid who is just so curious that you never feel a moment of peace? Give them this alarm and let themselves be entertained with the endless cycle of shutting off the alarm by waving their hand over and over again. We promise that you can never make $8/hour that easy.

Invest in our product and trust our vision, we will deliver an experience unmatched by others: an alarm so annoying that it reminds you to move every time that you stop.
