Polymer Journal Entry 4

In the beginning, Esther and I were confused and lost. We didn’t know what to do and we couldn’t think of any ideas. First, we wanted to make a polymer that could fit in your eat when you sleep. However, it would be dangerous to put a polymer in your ear because it’s not safe. On April 15, I thought of an idea. I realized that many students bring their phones in class and sometimes their phone rings. It happens all the time and all over the world. I told Esther about my idea of making a polymer that blocks the sound from your phone. Later on, we had class time to experiment on our polymer.

The first prototype was Gloop. We went into another room and used the Gloop to cover the part of the phone that produced sound. We were amazed that it worked on the Samsung, but it didn’t work on the iPhone. Next, we used all the different ingredients and the results were horrible. It looked ugly and disgusting and we regretted making a prototype using all the ingredients. We moved on to making Boogers. Boogers was the same as Gloop and didn’t have a big difference. The only difference was that it had more characteristics that we wanted. Then we changed the ingredients to make it better. We added 50 ml laundry starch, 2 cm of glue, and a few drops of food coloring. We mixed it all together and then placed it on paper towels to absorb all the excess laundry soap. Then we used our hands to make it into a ball. When class was over we put the new prototype in a plastic bag. The next class, the prototype became wet and sticky so we used the paper towel again to absorb the stickiness. Every time we made a prototype we would follow this procedure. In total, we made four different colors for our prototype, blue, purple, green, and pink.

This is when we started making our commercial. I wanted our audience to relate and connect to our commercial so we thought of real life situation. The commercial started off in a school environment and a student’s phone starts ringing. The teacher gets mad and the student is embarrassed. Then the student’s classmate introduces a product called ‘Sinslate’. We have a before and after video of the student using the product. We use this story line and add little bits of information in the video. For example, the price, colors, company’s name, etc. The name ‘Sinslate’ came from the words: Sound and Insulator. In the beginning, it was ‘Sonslate’, but it didn’t sound good so we changed it to ‘Sinslate’. Our company name is ‘Isoler’ because it means isolate in French.  

On the day we presented our product, I learned that the best commercials were the ones that had real life connections and the ones that had the target market audience in the video. For example, there was one group who had little kids as their target market audience. So they had a child in the video instead of a middle schooler acting like a little kid. Comparing from where we finished to where we started was a huge improvement. I learned many things along the way in this project.

Esther and I are almost done with our prototypes. We made good progress and going on the right track. In class, we continued where we left off last class. We finish our fourth prototype and we were happy with our results. Out of all the prototypes, we liked the fourth one the because we noticed that it had most of the characteristics that we needed. We fixed all the problems that we had and now we are thinking whether or not if we should have packaging and our products name. Some of the problems that we encountered were: the polymer smelling bad, the polymer being too sticky, and not insulating the ringtone. We first solved our second problem by using paper towels. We used the paper towels to absorb all the excess laundry starched that we used. Once our polymer was ready, we played with it to make sure it wasn’t sticky. Later on, we used Esther’s perfume and sprayed a little bit on our polymer. It solved our first problem and had now we had all the characteristics that we needed, except for one. The polymer had to insulate the ringtone and vibration. When we were testing the ringtone and the vibration in another room we realized that we were getting the wrong data. Esther and I went back into the science room because most classrooms are not completely silent. The teacher might be talking or other classmates are, so we decided to go back in the science room and asked our classmate if they could hear any ringtone or vibration sound. We tested maybe times by putting the polymer in a different shape and size. We learned that the best way to insulate the sound was to have a thick layer of the polymer and use it to cover where the sound was coming from. We were glad that the polymer didn’t go into the tiny holes because we wouldn’t our customers using it and noticing polymer stuck to the phone.

These pictures are the process of making our polymer. 


First, we added 2 cm of glue in a plastic clue. Then we added blue food coloring and mixed it together. Once it was mixed, we added 50 ml of Laundry starch.

After mixing in the laundry starch it looks like the first picture. 

We used paper towels to absorb all the excess laundry starch. After that, we mold it until it stuck together  in one piece. Once we were done, we put it in a plastic bag and labeled the bag. 

Polymer Journal Entry 2

Today Esther and I made three prototypes. Right now we have 4 in total. The first one was Gloop. To reach our goal we used our own phones to test it out. I used my iPhone 5 and Esther used her Samsung. We put our phones on the Gloop and played ringtones and vibration to see if the Gloop would block the sound. When we tested it, Samsung worked the best. It was very hard to hear the vibration sound and it was very effective. However, the iPhone wasn’t the same. You could still hear the vibration sound and the Gloop didn’t work. Later on, we tried to mix 3cm glue, 13 ml of borax, 12 ml of water, 20ml laundry starch, 5ml PVA, 1 drop of green, and 2 drops of yellow food coloring. We realized that it wasn’t a good idea because the results didn’t work and it didn’t look appealing. After our 2nd prototype didn’t work out, we moved on to our 3rd prototype. We used 1cm of glue, 2 drops of yellow food coloring, 26 ml of laundry starch, and another drop of glue. This worked out really well as well. It had the same results as our first prototype, Gloop. However, it had more characteristics than Gloop so we decided to use our third prototype. We wanted it to be flexible, easily removed, and easily molded. Our third prototype had all these characteristics so we decided to work on it. Because our third prototype didn’t work for iPhone, we wanted to make a polymer that was big enough to cover the whole phone. We doubled the amount of prototype 3 and started mixing. Because we didn’t have enough time the polymer wasn’t combined well together. Next class we are planning to improve our fourth prototype.

The table above shows you the characteristics of all the prototypes we made. The best one is the third prototype and the worst was the second prototype.



Materials we used for our second polymer: 3cm glue, 13 ml of borax, 12 ml of water, 20ml laundry starch, 5ml PVA, 1 drop of green, and 2 drops of yellow food coloring.(We switched the blue food coloring to yellow and green after the photo was taken) 


Our second prototype looked like this. It didn’t look good and it was very, very slimy and disgusting.  



Polymer Journal Entry 1


The first class we had when we started this unit was very interesting. We sat around Mr. Winkelman and he read us a story called, “Bartholomew and the Oobleck”. It was a story about a King wanting something new falling from the sky. He was bored of the rain, sun, fog, and snow. So he tells the magicians that he wanted something new falling from the sky. The next day, Oobleck was falling from the sky. It was green, sticky, and it made a mess. After reading this story we were told to make a polymer that was like Oobleck. A polymer is made up of a lot of molecules. When its all put together it makes a really long chain. The polymer’s characteristics are always based off of what it is made of. The look, stickiness, act depends on how the atoms and molecules are connected. Sometimes it’s really slimy, bouncy, smooth, and so on. My partner, Esther and I worked together and made 3 polymers. The first polymer was Gloop. The color was blue, it was smooth, bouncy, and smelled like glue. Gloop was made out of glue, water, and borax. When we did the slow poke test it came back up slowly. The fast poke was different, it came back up faster. When we did the slow pull test, it stretched and stayed in that shape. The Gloop was very bouncy. The second polymer was Boogers. Boogers was made out of glue and laundry starch. The color was red mixed with pink, it was slimy, and easily stretched. Same as Gloop, the slow poke test result was the same. Both Gloop and Boogers don’t change in the blob test. For the hang test, it fell apart after 47 seconds. Our third and last polymer was Super Slime. The Super Slime was really slimy and fun to play with. It stretches, but at some point, it breaks in half. Unlike the other polymer, the blob test so different. It slowly expanded a little bit. For the hang test, it broke after 67 seconds. Out of all the polymers, my favorite was the Super Slime.

In this photo, you can see the three different types of polymer that we made in class. The order of the polymer: Boogers, Super Slime, Gloop.


For our Polymer Project, Esther and I will make a polymer phone case that blocks the sound and vibration from your phone. We thought of this problem because many students bring their phones to school in class. While having class, sometimes their phone might ring and interrupt their class. This might make the teacher angry and get the student in trouble. We are planning to make a polymer for your phone that blocks the sound and the vibration coming from your phone. So the next time you go to class, all you need to do is, put on the case and you don’t have to worry about turning off the sound and the vibration. If someone texts or call you in class, your teacher won’t be able to hear it. You can also use this when you go to sleep. You can put the case on your phone and you won’t wake up in the middle of the night. Even if you don’t go to school you can use this polymer. You can use it during work when you are teaching a class or  in a meeting. Our target audience is for anyone that has an iPhone or a Samsung. It can be used during school, work, and sleep. We will need perfume, paper towel, cup, spoon, laundry starch, glue, and food coloring. We are planning to make a polymer that doesn’t smell bad, can block sound and vibration from your phone, moldable, flexible, easily removable, able to stick, and easy to use.


In this picture, you can see the four prototypes we made from the past few class. Esther and I made 4 prototypes in total.
