What will the polymer be like?
Physical properties of our polymer include:
The polymer should not break very easily when stretched very wide or pressed down with a moderate amount of force. Otherwise, it would not be useful to hold anything together.
No one likes an incredibly sticky or wet slime. It gets everywhere – on clothing, on desks, on the skin – and is hard to get off. A sticky polymer would not be useful for our design either.
A bouncy polymer will feel less slimy and will stick to fewer surfaces. It will also be less likely to break when dropped. All of these characteristics are ideal for a moldable rope-like design that we are going for.

How will the polymer be tested?
After the creating stage is completed, the polymer will be stuck to surfaces, wrapped around small objects, pushed on, poked, molded, and stretched into a long, thin strand. It will also be left out overnight to dry. These tests are to ensure that the polymer fulfills (or does not fulfill) the desired physical properties. A good prototype should be maintaining these properties.
The polymer that I (we) want to design is for a very specific situation but could potentially be helpful.
It will be similar to this design, protecting the wire from being broken and also holding it together to prevent the earbuds from tangling. The targeted audience is, if not obvious enough, people who use earbuds, namely people who experience the problem of untangling earbuds that have unfortunately been coiled together several times in their pockets.
This polymer will hold earbuds in a neat position, making them a lot easier to unravel.
The relative lack of stickiness in Gloop makes any polymer with this characteristic ideal for attaching to items. I also liked the simplicity of Super Slime, which consists of only two materials. Adding more of one material would make the substance more watery and less solid, adding more of the other would make it thicker and drip less liquid.
