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.
