The problem we were trying to solve is the trying to slow down the speed slower than usual. We solved it by adding a type  of heater that adds the heat up more and then decrease the amount of time that decreases the heat loss.

We did the heat in the first place which is still pretty small heat and loses heat pretty quickly at first but it only lost about 20˚ in total, but we also gained heat because of the places that it can rebound the heat back into the cup sometimes. This is the picture of the insulator:
