Slightly racist clock helps me wake up

A lot of these posts seem to be about me sleeping and here's another one on the same subject. I'm a very deep sleeper and it takes a lot to wake me up. As you saw in my Physics video, even when I wake up, I fall right back asleep. Many times I've been nearly late to school and people have laughingly told me later that they saw me running to school as my pants fell down, my backpack flew wide open, and I nearly choked on a bagel. Although I showed in my video that I use my cell phone to wake me up, I actually utilize a total of 5 different alarms. I have created an elaborate scheme where some alarms are near me and others are strategically placed around the house so that I am forced to walk around and turn them all off, thereby waking me up. Even with this set up, I sometimes fall back asleep. Therefore, my mother finally recommended that I get an alarm clock that vibrates, as this is the type of alarm that deaf people use to wake up. I thought "coolio" and couldn't wait. However, the alarm I received, while it does vibrate, came with another feature I found slightly disturbing.

This is the clock on my bed near my pillowIt looks a little funny, but innocent enough. However, the first night I used it, I was a little surprised when I heard someone with a horrible Indian accent telling me to wake up. That is because this clock, called the Timex Wacky Wake Up clock (horrible name) comes jam packed with 7 messages delivered by horrible stereotypes including a Mafia member, Redneck, and African-American activist. It does vibrate but the messages that come along with it, while funny in a guilty pleasure sort of way at first, became really annoying. This is a link to Youtube with all 7 messages if you want to hear them. They're good for a laugh once but after hearing them over and over, I'm frankly sick of the clock.

Anyways, this clock, like so many things in life, is another good example of Physics in action. The clock creates longitudinal sound waves by vibrating air within the clock, which escapes via a series of holes in the side of the clock.
The different pitches of the very bad accents are caused by differences in pitch and timbre in the voices. Pitch, determined by the frequency of the sound waves, determines what note the voice speaks in and at what octave. The different voices have different timbres. Timbre is the mixing of many different frequencies so that the same note can have different sounds. The multitude of voices are very different because of their different timbres. And finally, the vibration that I wanted the clock for is created by a small motor in the clock. When current flows through it, the motor spins and weights attached to this motor spin as well, jiggling the whole clock and causing the sensation of vibration. This simple seeming clock is chock full of Physics concepts including the buttons that work because of capacitors and the polarized LCD screen but I won't bore you. One thing that's scary is that now that I've had the clock for a few months, I subconsciously know the order that the voices play in. Man that's creepy.
