Bottles

nickel alloy, help make a sturdy rocket. For the bottle rocket, my partner, Maren Cheney, and I used the following materials: 2 plastic 2-liter bottles, office folder paper, clear duct tape, yarn, 2 sponges, and cotton. The payload of the rocket is the object(s) being carried throughout the flight. While the payload of real rockets include astronauts and satellites, our bottle rocket had an egg to represent the payload. After finishing the bottle rocket, Maren weighed the rocket to get a mass of…

“This is by far the worst water quality we’ve ever seen in our sailing careers,” said Ivan Bulaja, a coach for an Austrian team training at Guanabara Bay in Rio de Janeiro, where the 2016 Olympics will be held. The waters are polluted with sewage, dead fish, and trash, posing a serious threat to athletes training or competing there. Kristina Mena, a professor of public health, is an expert in water quality, and conducted a risk test for athletes competing in the waters Rio, assuming they would…

factor, compared to the price of gas today it costs more for a liter of bottled water than the same amount of gas. Tap water also creates a much more dependable source of water. With the use of tap water also takes away from the 81.7% of plastic bottles found in the landfill each year. Water itself seems harmless, but what is really in it? In all honesty, there is no real similarity between tap water and bottled water. About 25% of bottled water comes from a public supply. This water is then…

What we did for our project was create water bottle rockets. What I all learned from making water bottle rockets was really interesting. We figured out that the smaller the rocket is, the farther it will go. The reason it will go farther is because it has less weight on it, although some big rockets will go pretty far too. What I did for my rocket was get one 1-liter bottle and cut out four triangular cardboard fins. After doing that, I hot-glued the fins towards the bottom of the rocket. When I…

We’re getting feedback on our mid-term photo-shoots in today’s class. 
A guy named Rick is currently bragging about his new take on the theme of “jungle” that consists of pictures of girls wearing spotted clothes in what I think is Central Park. Astonishing, really. 
Nobody seems particularly impressed. I glance at Grace from over my folder and I can see her narrowing her eyes, in the way she does when she’s trying not too be too critical. She’s too good to be a teacher. She won a Pulitzer for…

Cleaning auto glass might seem easy at first. However, soon after cleaning your windshield, you will probably notice streaks on the windows—which are unsightly and potentially dangerous. Fortunately, you can take some steps to ensure your windshield is clean and streak-free. Here are five tips for getting clean, streak-free windshields: 1. Temperature Matters If you are like most people, you probably wash your vehicle on hot and sunny days. While warm, sunny days are ideal for cleaning—the…

Discussion It can be seen from the experimental data, that the relationship between the difference in initial pressure inside the bottle rocket and the atmosphere, and the vertical height reached by the bottle rocket after 0.1 seconds, is proportional. This is quantitatively demonstrated by the high R2 value of 0.99533 of the graphed relationship, which indicates the likeness of points in a data set to an established trend; where 1 = a perfect relationship. The gradient of 0.0236 in the…

1.Elmer's Bottle Tree Ranch Located in Oro Grande, Calif., Elmer's Bottle Tree Ranch has an abundance of unique tree sculptures made out of antique bottles. The site is located along National Trails Highway. The bottle tree sculptures are the work of the ranch's owner, Elmer, who began making them 15 years ago when he inherited his father's bottle collection. Elmer lives on the property, and he tends to interact with his visitors. The attraction is home to over 200 bottle trees along with other…

mom’s death our dad tried his best at being strong. He lied to us, giving half-hearted speeches to me and my sister about how he was fine. His facade crumbled away after he saw mom’s coffin descend into the ground. He later found solace with a beer bottle. Every night when I tried to sleep my nose was invaded with the bitter stench of alcohol. On a few occasions, I could smell a musty scent in the air when my dad lit up a cigarette in the house. The putrid smell was so strong and so revolting my…

For my group’s project we changed the size of the woosh bottles to .5, 1, and 2 liter bottles. I learned that the size of the bottle strongly affects how far the bottle will travel. The larger the bottle, the farther it travelled. I learned that the chemical reactions in the bottle with the ethanol and the flame creates energy which propels the rocket. The ethanol is also ‘absorbed’ by the fire of the match. If the bottle was larger, it was covered in more ethanol and had more oxygen in it,…
