Spill Proof Mug

The other day I came across something talking about a spill proof mug. Since I do tend to spill drinks occasionally, I wanted to read about it. The cup uses a suction on the bottom of it to help prevent it from tipping over. Once the mug forms a seal with the surface it is on, the air pressure under it becomes smaller than the atmospheric pressure above the cup, resulting in the downward force keeping the cup on the table. Even when a small force is applied to the top of the cup that would

Jet Stream

When I flew to California and back last month, I noticed that it took more time to fly to California than it did to fly back to Rochester (even though it seemed shorter to fly to California because of the time zone difference). This happens as a result of the jet stream. The jet stream is a strong and narrow air current the circles the globe flowing from West to East. Jet streams occur because of the heating of the atmosphere from solar radiation and the Coriolis effect from the Earth’s axi

The Magnus Effect

The Magnus effect happens to a spinning object that drags air faster on one side, which causes the object to move in the direction of the lower-pressure side. Here’s a video showing the Magnus effect in action:   Newton’s third law helps to prove the Magnus effect because the object pushes the air in one direction and the air pushes the body in the other direction, an action-reaction force. With a ball spinning through the air, some of the air spins around the ball with

How to Get the Most Out of Studying

Video 1 a.    4 beliefs that make people stupid: ·      Learning is fast ·      Knowledge is composed of isolated facts ·      Being good at a subject is inborn talent ·      I’m good at multitasking b.   I tend to try to multitask while doing homework by checking my phone every once and a while, but then I have to go back and reread so in the end it actually takes longer c.    Metacognition: A student’s awareness of their level of understanding of a topic

Air Resistance Tests

Last night my younger brother was watching one of his favorite shows: street science. I happened to walk in the room as they were doing a Galileo-inspired experiment where they were dropping different objects from a crane to show the effects of gravity and air resistance. At first, they dropped a basketball and a bowling ball from a height of 50 feet. Physics tells us that both objects should hit the ground at the same time because in free fall the weight of the object doesn’t matter. Howev
