The Gloop and Guar gum prototype was not the right prototype for us because it was too sticky and slimy, so if we put that on the door handle, the person’s hand would be stuck onto the polymer. The Guar Gum that we added did not have a big effect on the polymer, the polymer had clumps of Guar Gum in it after we added it, that would not work because we need the polymer to be comfortable when touching it.
The Stretch-tastic was too slimy so we added some cornstarch to it to make it thicker, it worked out really well, it was really comfortable to touch, it was malleable and it was not sticky. This would make the door handle cover really comfortable. The Stretch-tastic does not hold heat as well as the Gloop, but it still holds heat for a long time, this would make the door handle cover really warm so that people’s hands will not be cold in winter.
Another Prototype that we made was the Gloop and the Guar gum mixed together, we found out that it preserved heat longer than Gloop and stretch-tastic, but we did not use it because it was not malleable.
