Polymer Journal #4


For every prototype we created we tried creating a polymer that satisfies Aaron comfort. Our general rule of thumb was if Aaron liked it everyone likes it. I believe our first prototype was flexible and stuck to anything pretty easily but it didn’t satisfy Aaron. Our second prototype was not as flexible as prototype 1 and it ripped easily but it was a bit more comfortable. Prototype 3 was our best out of all of them we also changed it the most we took prototype 1 and added more glue, on top of that we put some cornstarch. We asked multiple people and even Aaron said it was good, when we tested it with a golf club Aaron said, “it actually feels really nice, I’m not even joking that actually feels really good. This polymer is dope.” The only limitation is that when people are playing golf it will hot and you sweat when your hot. Once your sweat comes in contact with the polymer all the cornstarch will become wet and it will become all slimy which will make Aaron get grossed out. Our final prototype was a complete fail, more people liked the feel of prototype 3 and it broke easily. It had its strengths it was able to mend easily if it ripped but at times it can get messy. Our first designs didn’t really have that big of a change it it did help a little bit. The first two prototypes we changed the amount of water we put in the polymer. The third prototype we added more glue which made it more solid but it still felt a bit slimy so we added some cornstarch which was perfect for Aaron. The last prototype we added liquid PVA instead of white glue it made it very fragile which was not good for us but it still had some of the standards we wanted. As I write this I have thought of new ideas such as using half white glue and half PVA. For our final design prototype 3 you need to add 30ml of glue into a beaker, 8ml of borax into a graduated cylinder, 5ml of water in a separate graduated cylinder. After you have everything put it all into the beaker and mix with a stick once you think you can’t mix anymore take all of it out and use your hands. After it is a nice solid piece of polymer add one scoop of cornstarch and spread it out. And that’s how you make our master piece.

Here is the evolution of our prototypes

For our golf club grip we want our polymer to fell nice and squishy but not too wet, we also want the polymer to reduce blist
