Breaking CDs

A YouTube channel I enjoy to watch is that of The Slow Mo Guys. For those of you who aren't familiar with them, they film many different things- paint on speakers playing music, a bullet being shot through a pool of water, etc.- with high speed cameras that capture millions of frames per second. In one video, they spin a CD at 23,000 rpm (the critical spin rate of a CD)  at which it begins to shatter due to the extreme forces it feels at this high rpm. They catch all of this in slow motion makin

Dog and Cat Wars

I own two wonderful pets, a dog, Henry, and a cat, Willow. Let's just say they... tolerate each other. As my dog has gotten in to his elder years (He will be 11 this August), chasing the cat (she's turning 5 in June) has become less interesting to him. I've noticed on the days he does decide it's worth it to get up and run after her, she is able to turn the corner a lot faster than he is. I figured this must be because of her lower center of mass. She can turn at a lot higher speed without her l

Air Bags

Once upon a time, air bags were nonexistent. Now they are a standard feature in all new cars. This became a requirement for cars in 1998. When you get an accident at a high speed where the vehicle stops quickly, we know that the person inside wants to keep moving in the same direction at the same velocity as before the crash. Seat belts help to prevent the body from slamming into the wheel or flying out through the windshield. Your head can still fling forwards. The air bag deploys in order to s

An Octopus' Garden

The title of this blog post is pretty irrelevant except for the fact that I will be talking about an octopus. The said octopus was won by a friend of mine for selling a bunch of a certain item for a class fundraiser (good job making those sales- woot woot!). The octopus was one of the gel forms that sticks pretty much anywhere. We threw it against the wall cabinet in the physics classroom and watched it stick for a short amount of time before it started to slide down. For a brief period of time

Laundry Mishap

About a week ago, I walked down into the basement to check on my laundry only to find a large puddle of water on the floor. We had temporarily fixed the pump that brings the water from the basement up into the septic but it seemed to have broken again. We need pumps for appliances below our septic tanks because the water does not have the ability to move from low to high (high being the location of the septic tank; low, my basement) without an external system doing work on it. Because of gravity
