For this video reflection I watched a video on how to create Prince Rupert’s glass. The first time I watched the video I was convinced that the glass they were using was some sort of plexy glass. The reason why I say this is because, when the glass broke it didn’t crack or sadder, it completely deformed. When I say deformed I mean, it transformed from a solid object to a dust like substance. After watching this my thoughts of Prince Rupart’s glass completely changed. Over all I learned a lot from watching this video. I learned the difference between tensile strength and vibration, as well as why the Prince Rupart’s glass shattered like it did. The Prince Rupart’s glass because of the vibration, and the reason why it is so strong is because the tensile strength is extremely high.
1: Why is the tensile strength so high?
2: Would the tensile strength of the Prince Rupert’s glass change exponentially if the mass of the glass would change?
3: What type of technologies can be created with the knowledge of the Prince Rupert’s glass?
4: What type of frequency does the Prince Rupert’s glass set off when it is shattered?
5: If the Prince Rupert’s glass was reheated and re cooled would the tensile strength get greater, or weaker?
How do rockets work.
February, 23, 2015
After watching this video on rockets I learned several thing’s. Although the majority of them were just refreshers to what I’ve learned in the past, I still learned an exponential amount. I learned that the key in rocketry is newtons first law of motion. “Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This we recognize as essentially Galileo’s concept of inertia, and this is often termed simply the “Law of Inertia”. Which translate’s into for every positive or negative action there is a positive or negative reaction. When it comes to creating a rocket, this rule is key in making an successful rocket. The reason for this is because a successful rocket needs the proper amount of thrust as well as several other necessities to lift the object in the air. The thrust that is coming from the bottom of the rocket, is the action, and for action there is a reaction. The reaction being the rocket separating from the thrust. Surprisingly I learned a lot from this video, and now that I am more knowledgeable about how rockets work, I plan on continuing my rocketry path.
1: Is the fuel inside of nasa’s rockets a liquid or a solid? 2: What prevents the rocket fuel from combusting at the same time?
3: Rockets, are the definition of Isaac Newton’s first law. For every action there is a reaction. But wouldn’t gravity prevent this from happing because its constant push on earth?
4: For every action there is a reaction, correct? If so why isn’t the object that is reacting going at the same speed as the action?
5: Will an air powered rocket every be able to go space?
How to make sugar rockets.
February, 23, 2015
After watching this video I was amazed. I was amazed at the fact that just a few simple ingredient could create, an oxygen inhaling flame. After watching this video I learned a lot about how just a few ingredient’s could create a rocket as powerful as gas. A few of the ingredients that are required when making a Sugar rocket are. Sugar, Potassium Nitrate, a Grinder bowl, a Cardboard tube, and wood tube. The video on how to create a sugar rocket was extremely descriptive and extremely useful. Which is why I am so successful at making rockets. Although making these sugar rockets are super simple, there extremely complicated as well. In order to create an excellent rocket, many things are needed, such as the ingredient’s, the tools, and the proper proportion’s. To start making a Sugar rocket your going to need thirty five grams of sugar, and sixty five grams of potassium nitrate. Once you have these materials your going to need to mix them/grind them into a fine powder. Once this step is complete it is optional to add an oxidizer. An oxidizer is material that controls the burn. Iron oxide is the best form of an oxidizer. Once you’ve added/mixed all of these materials together your going to want, to start packing your rocket. Once your rocket is packed, your ready for launch.
1: What exactly is it that is in sugar that makes it flamable?
2: What is height of the highest sugar rocket ever launched?
3: What would happen if we launched a sugar rocket from underwater?
4: Why does the proportion of sugar have to be less then the potassium nitrate?
5: Can a sugar rocket be used as a bomb?
How do rocket engines work.
February, 23, 2015
When I begun to engineer my rocket, and rocket engine, I had already gave my self a jumpstart. The reason why I had already given my self a jump start is because, before I begun to build my scratch rocket, I spent the time to get familiar with the materials and how they were used. When I officially started my rocket, I begun with making the body of the rocket. I used two inch thick by thirty inch in length brown pieces of paper, and cross wrapped them with wood glue along the pvc pipe mold.I repeated this step three times, and let it sit over night. Now that the wood glue has dried it has bonded all of the pieces of paper together, and I am ready to remove it from the pvc pipe. In order to removing it from the piece pipe I had, to cut both ends of the paper off, releasing it from the pvc. Now I am able to start making the fins, and the rocket engine. To start your going to be using a scale. Your going to measure 14 grams of potassium nitrate or saltpeter (KNO3) and 7 grams of sugar. This makes enough propellant for a single 2"-long rocket motor.
Blend the ingredients by placing them into a tightly covered plastic container with a handful of large lead fishing weights or .50-caliber lead balls. Then shake, shake, and shake some more. This is a low-budget method of ball milling, a method that pyrotechnicians use to safely grind and mix volatile chemicals. The longer you shake, the better the mixing and the better the rocket fuel.

Can silence actually drive you crazy.
February, 23, 2015
Many may assume that silence can drive one crazy. After years of science experiments, and thousands of dollars down the drain, scientists have come down to one conclusion. Silence can drive someone crazy, but not everybody. When I started watching this video, I begun internally laughing. I knew that there was no way silence could drive me crazy...... At least thats what I thought. After watching the video and learning the science behind silence. I was still not convinced. I knew that I was going to have to try this out my self. So I went down the hall at school , and enter into the sound proof recording room, my school has. I turned on the timer and stepped in. I stayed in the room for around twenty minutes and started to hear weird things, this is when I realized that sound could actually drive me crazy. 1: What are the foam slices made of?
2: How many people have gone crazy in these rooms?
3: Does hearing depervation change if you exit a room of silence into a normal room?
4: What would happen if someone were to be locked in an all silence room for years on end. Would their hearing adapt to smaller sounds/frequency’s?
