Journal Entry# 4- Final Reflections

Fraser Y 8-2

 

 

 

Thinking of a polymer that had a medical use was pretty easy to me, it was something that sticks, and comfortable to hold, and only a few earlier recorded tests was needed to make sure which polymer was the best choice. My first choice was Super Slime as it is easy to mold, flexible, and comfortable. It also sticks will, so I decided on that. Through the Developing Solutions stage Calvin(Lin) pointed out that although the Super Slime was comfortable on skin, it was a bit too slimy. This made me think and we looked back on our research to see which other polymer can be a better substitute, but no other single polymer is a better substitute, so I decided to make Goobers as it is used as a thickening agent, but because Goobers are very hard to make and it might kill off the Super Slime’s goal of being able to flow around, Goobers was out. I then decided that maybe adding some Gloop was a good idea. The first prototype with Gloop failed miserably; it was easy to handle but was not sticky at all, meaning that it won’t meet its goal to stop bleeding. I soon found out that the Gloop had overpowered the Super Slime. So I decided that if I can add a smaller amount of Gloop it might work. When I did it, the stickiness worked and the handling. Sadly, the polymer was not as stretchable as it used to be with only Super Slime. Calvin suggested massaging the polymer with Elmer’s Glue. Amazingly, with enough massaging, glue and patience the polymer became very flexible, more comfortable to hold, and even works better in out testing stage; compared to Super Slime.

 

We had three ideas for testing, the first one was to slit the plastic mixing cup, then put on the prototype to test how strong it can hold against a force of steady water. We realized that this wasn’t a very good idea as there were very few variables (and best if you not know them; or our product will be a failure), so then we decided that maybe ripping a piece of paper, apply the polymer and then pour water was a better idea. With some light thinking we had to scrap that as it was even worse than the plastic cup. There was no idea if the prototype will work (as it is running tap water and may soak around the paper). Me and Calvin were in thought when I noticed the food coloring on our table. I came up with the idea that maybe we should put drops of food coloring on the paper instead. This way we can actually see if the polymer can work. And so the bandage test was born.

 

During the Dream On presentation, I realized that our infomercial was too much, we explained to many details about the polymer. I then realized that everyone else’ was more of a commercial if it was compared to Slap Chop, one of the world’s most renowned infomercials. We did good on the countering questions part. Where other groups got up to ask us question, our group was the few that actually had a polymer that reached its goal (or so I think).

Rat City!

April 26, 2016

There are about 1 million people living under Beijing. All of them living in bomb shelters that Mao ordered to built to protect people against the Soviet Union. Most of the people coming here are young and is looking to set a foothold in the most important and favorable city in China. It is the place where dreams of making it big come true with a bit of hard work, and to start that, a bomb raid shelter is the perfect place to live. About 1% of the people living in china live underground; most of them migrants. The bomb shelters is a perfect place to live as it is privately managed, and it is very cheap. Cheaper than anything above ground. Many people living here work at small jobs and earn very little, but all of them are very happy living here. Which is very different from above ground where a lot of people will argue about money, in the bomb shelter money is plentiful, especially because of the low rent. Some people will move out here if they become successful, with one making 800 kuai to 4800 kuai every month! Some people, still stay here, even when they are successful, when asked, they answered that they have grown used to waking up in a windowless room and that the rent is very cheap. Living in a few square meters above ground will cost nearly double than what it costs living in the air raid shelters. Almost all 30 000 air raid shelters is under government control to earn profit. Some of these air raid shelters go to private management. Now, living underground is a very big thing, although with tightened security from the government, it is unsure wether this trend will continue. The government used to allow people to live underground, but with the bad influence to Beijing, the government is now kicking people out. Natural disasters are also a problem as all haven will be already taken by the so called, “Rats.”

The environment’s pollution has effected the society in negative ways. With a big increase in deaths in cancer, 380 000 deaths blamed on pollution each year, and 400 000 premature deaths each year. Sadly, people haven’t done the same for the environment. China placed several factories that use old machinery to save money. These machines aren’t up to code with the modern environment. Meaning that they are not efficient, the factories then pollute the environment with speed and a lot of particles that can kill. With only very little new factories using the newer energy efficient method. A lot of political candidates have been saying to people that if they vote for them, the environment will be much better, and the government will make saving the environment one of the top priorities, and if officials in the system disagree, their name will be called. Apparently these candidates are suspiciously using this just to win over votes as none of what they promised are actually in place yet. Humans are using the environment to have a stable economy; and one that grows fast too, but the environment has revenge to the people who cut trees down, pollute the air, and extract coal without a thought of the consequences. The environment makes the air hard for humans to breathe, coal mines collapse from the weight of the rock, the food chain is cut short with no environment for some animals to live in. If this keeps going on the pollution will double in shorter years than expected, with deaths rolling in like waves for the 99% who can’t breathe in fresh air. Coal mining will be a dangerous business, and people will have limited access to clean water and a variety of food will be scarce.

 

This will happen if there is no action taken to help the environment. Humans will do anything to save money, and if China continues on this path of environmental destruction, they will lose a lot of people, clean water, and safe food.

Journal Entry #3-Optimizing Prototypes
Fraser Y 8-2
Sadly, Prototype #2 where Super Slime is added with Gloop did not meet the standards. Prototype #2 had much better handling, so applying the polymer to a damaged area is much more efficient. Sadly, the Gloop mixed with the Super Slime, instead of layered. This eliminates the Super Slime’s main goal of making a physical barrier to stop bleeding. With that in mind, the plan is to go with the original prototype, although the handling could be better, adding Gloop to it will not work. Boogers will be worse as it is slimier, making it the worst-case scenario. A new prototype that I am thinking of is to add a very thin and tiny piece of Gloop to the Super Slime. Originally, it was layered successfully, but both are pretty sticky and with a few bumps, they stuck together. Further observations can be made that the Gloop was larger than the Super Slime, probably the reason that Prototype #2 had failed in its blood barrier test. (As Gloop engulfed Super Slime entirely) If Gloop decreased in its size, at least half it might be the best of both worlds. As then, Super Slime can actually be effective. Layering them will also be easier, as it is harder for Gloop and Super Slime to stick together. A test will have to be appointed out.

IMG_1482Careful Observations can be made that the Super Slime is totally engulfed in the blue colored Gloop.

IMG_1488Here is a bit of Super Slime that got engulfed in Gloop. This Super Slime might is half of the whole Super Slime mix that got drowned in Gloop.

If the test is successful, then the final design plan will be to use the new design in which we use smaller sized Gloop and attach it to Super Slime.

We have tested out the new prototype, and it was very successful. Yet, it did not stick well, so Calvin came up with a plan of massaging Elmer’s Glue into the polymer. We decided to try it out, first by dumping a reasonable size of glue on each side of the prototype, then by massaging it until the glue is not visible, but still very sticky to the touch. Finally, we washed it and tested it.

The conclusion: After applying glue to the polymer and massaging and mixing up all three (Gloop, Super Slime and the glue) the end result was very successful. It stuck much faster than before, it was just as stretchy as before, even with the Gloop (considered easy to rip apart rather than stretch). Finally, prototype #3 stops blood EVEN BETTER than Super Slime ITSELF.

IMG_1627When Protoype #3 was tested, no green food coloring showed up on my hands, even when I added 6 drops of green food coloring to it. It also easily came off, no fuss and no mess.

IMG_1629Prototype #1 was tested under the same controlled variable, with the same rip, same number of drops of food coloring, and same place of application, yet, my hand came out with a lot of food coloring on it. It stuck to the piece of paper when I tried to pull it out. Bits of Super Slime still stuck to the paper after I finally pulled the polymer out.

Each polymer has properties that will be useful to stop bleeding. For example, Gloop rips easily, making it easy to find the right size. It is also the least slimy, but it is too bouncy. Yet, it sticks well. Super Slime on the other hand was very good at the blob test, making it easier to seep into a cut and make a physical barrier to stop the bleeding. Boogers is not a very good consideration as the drawbacks outweigh the benefits.

 

I am thinking of doing combining Gloop on top of Super Slime. Like a bandage, Super Slime will be the part that cannot be touched while Gloop is the part that can be touched; this will make applying the polymer to a cut easier as Gloop is not that slimy. I will make the Gloop first, let it become a blob, as it takes longer than Super Slime. Then, I will make Super Slime and wait until it too has become a blob. I will slowly push the Gloop and Super Slime together, until they stick to each other. (They are both sticky so it won’t be a problem)

 

Testing the prototype won’t be that hard, as the final product is to stop mild to hard bleeding fast. A way is to make a rip on a plastic cup, apply the prototype without force, and fill the cup with water, to see if the cup will leak. Another, simpler testing method is to make a tiny rip on a piece of paper, apply the prototype, flip the paper over (to simulate the inside of a cut) and pour a few drops of food coloring. This will test how effective a little piece of the prototype can stop mild bleeding, cleanly and efficiently. Finally, I will put the prototype on my arm and turn it around, to see how sticky it is. This test is to show if the polymer will come off the arm easily, if it does, some steps need to be taken.

Journal Entry #1-Defining the Problem

Fraser Y

Today, we plan out a polymer that has a medical use. The first thing that came to my mind is something to instantly stop bleeding. We decided that that is the easiest and most affordable way to make a polymer that can have an impact. With that in mind, Calvin and I looked up other polymers that stop bleeding, the most famous being Vetigel, the purpose being a way to stop bleeding for pets. We can make a polymer that is for human use. Calvin set out to find the right polymer for it. He picked Super Slime for it’s amazing blob capabilities. The sad thing is that it is not sticky. I decided making a mix of Goobers (For its sticky and easy to handle capabilities) and Super Slime (from ball to flat in half a minute) may be a good idea.

*Update: If left for about 10 seconds, Super Slime turns very sticky, this eliminates the need for Goobers. One problem though, is that excessive materials from the polymer will not be easy to peel off of the skin after it stops the bleeding. Super Slime will seep through the cut of the skin to create a physical barrier to stop the bleeding. The target market audience is for people who want to create an extra barrier of safety and to ensure that they have fast and useful medical aid by their side. The polymer can be re-used and it is quite cheap. I also hope to make the polymer softer and pliable so that it can stop bleeding more efficiently and can be applied to hard to reach places. Another way is to put the polymer into a syringe and sell it that way. This is easier to apply and safer, but won’t be as effective, so the polymer needs to be more foam like, similar to our competitor Vetigel.
