Have you ever thought about unfathomable numbers? Like 6.02 x 10^23. That would be a mole. A mole of skittles would be 6.02 x 10^23 skittles. That amount of skittle would fill the Grand Canyon, and then some. That's how huge a number that is. Surprisingly though, moles are around us at all times. Not just the burrow-y ones (sorry, that was a bad pun waiting to happen). Say, a mole of Carbon weighs exactly 12 grams. Just twelve grams to contain 6.02 x 10^23 atoms of Carbon. To put this in perspective, this is the number expanded= 602,000,000,000,000,000,000,000. This is huge. If you have a mole of pennies, you could give every single person 1 million dollars every day for 2500 years. This would cover 216,721,026,000,000,000 cubic meters. That's a factor of a thousand away from filling the entire Earth. You could cover the Earth in pop cans. Not just once, but a layer about 200 miles thick. Then back to the Carbon example. About 12 grams of Carbon is a mole. Just 12 grams. This proves how insanely small atoms are. My mind=blown.
Graduation is definitely a bitter sweet time (original topic, i know!). But really, it gets me thinking about just how much change is present in our every day lives. Maybe someone dies, loses a job, gets injured, has to move far away, etc etc. These are all things that can drastically alter a life, and they all can happen so fast. The same is true with graduation. After the seniors graduate, their lives will never be the same. There will be people they have went to school with for the past 12 years that they will never see again. They may never even return to Aurora! Some are joining the military, some are going off to college, and some are taking a year off to travel or just save up money in order to afford college. Regardless of what they are doing afterwards, nothing in their lives will ever be the same as what it was when they were in high school. It's not only their lives that are affected, it's the same for the underclassmen. I wont be able to discuss IB stuff with the senior class anymore. Some of the seniors that starred in the last couple of shows may never grace a stage with their presence ever again. And well, that's all the bitter stuff. The sweet part? Grad parties.

Okay, so you know how you can sing high enough to break glass? It's actually easier than most media makes it out to be. What you have to do is sing the resonant frequency that matches up with the natural frequency of the glass. Basically, everything has a frequency at which it naturally vibrates. So, if a note is sung, or played whatever, the object starts to vibrate along with it, causing more sound to be produced, causing it to vibrate harder etc etc. Make an object vibrate hard enough, and it will shatter. Obviously, the easiest type of material to do this with would be glass, considering, well, it's glass. And, the other thing I've found is that the resonant frequency isn't all that high, I could even hit the note after a warm up. The main issue with the process is that the note has to be played at extremely close ranges and extremely loud. So, put an amplifier right next to the glass. Yeah, I'm gonna break glass with my voice. This is gonna be awesome.
