Recipe:

-white glue 150ml

-corn starch 2 spoons

-borax 50ml

-guar gum 1 spoon

The procedure that we made our polymer is the following:

1. Add in 150ml of white glue, 2 spoons of corn starch, 50ml of borax, and 1 spoon of guar gum into a beaker.

2. Mix all the materials together in the beaker

3. After it  is in the shape of a polymer (harden), take it out of the beaker. Stretch it until it is stretchy and test it on table corners.

I think the polymer we made with white glue and borax was the most successful. It was very stretchy and and easily shaped. We had different prototypes and some were not stretchy, so it wouldn’t protect the corner, it would just fall off directly. Other prototypes were too slimy, which means that it would stick on our clothes or skin. Back to journal 1 when I researched about polymers, the polymers we are making is called artificial polymer, which means that it is not 100% made out of natural materials. The polymer we made was made out of borax, which is a toxic material. But only using a small portion of it would be fine. And our material is made for protecting the corners not to eat or put on skin for a long time. 

I think our plan is overall successful. During the planning stage we quickly decided the product we were going to make, then we started to make our prototypes. We tested all of our prototypes to find out the best product. And at last we created a pitch which is a video to show our audience the characteristics of our product. I think our video is pretty successful because we added in how the product could help us in life. However, we missed some parts, like the sustainability and the pros and cons of the product. So, we decided to talk about it after the presentation. I think our polymer is sustainable because clients could re-use the product and it would still stick, so it has a positive impact to the environment.
