Apples and Buses

A few days ago, my volleyball team traveled to another school for a match (which we won, even with the touch I called myself on that could have scored us the winning point if I hadn't) and for our trip home, the opposing team gave us a huge bag of apples. So as we rode the bus home we ate and then we had 15 apple cores and no idea what to do with them for the rest of our 45 minute bus ride home. An open window sparked an idea and with that I became the center for the discard of our apple cores.

DSLR vs. iPhone Cameras

Plucking is when whoever is playing the instrument uses their finger to pull up the string and let it go. I believe this is more commonly seen with guitars (I play violin and it doesn't happen to frequently in the pieces I play). All of these instruments have strings that are fixed on each end.

Lasers

It's common for lasers to be included in high intensity, spy movies (so I've heard). I've really only seen them in kids cartoons since I'm not well versed in current movie culture (I really only watch romantic comedies-whoops). KIDS!! You are being fooled! You can't actually see a laser beam when it's pointed across a room. Those red lines that you have to tentatively step around to avoid setting off the alarms would not actually be there in real life. Why is this the case? Well, laser
