Glue Polymer Lab Investigation-New variable

This lab investigation did surprise me. I thought if we doubled the borax solution then it would not bounce. I was right, but not for the same reasons. I thought that if more borax was added it would become slimy and liquid-like but it became thick and sticky. What I figured out was that the borax solution was cold, adding it to the glue creates a cold, thick, sticky, flexible and a not bouncy polymer. Six minutes later, when it warmed up to room temperature it was capable of bouncing up to six centimeters! The texture was much duller, or not as sticky. The refrigerated polymer was really sticky, more sticky than when it was first made. Yet it did bounce higher than when it was just made. It bounced 2 cm. A variable that might have changed the results was that we did not have enough time to keep it in the fridge the full amount of time. In the process, when actually combining the components another variable occurred. The polymer became saturated and did not accept the full amount of borax.

Comparing this polymer with the first one with half the amount of borax we can tell that borax is the main component to cause it to bounce. That and the temperature. Polymer #1 had a duller texture, bounced higher, and even higher when refrigerated. That confuses me because when polymer #2 was colder then when it was originally was made, it bounced 2 cm compared to 0 cm. What I thought caused this was the sticky consistency. When it was bounce it stuck to the table, but when it was not as sticky it had a chance to rebound.
