We were trying to solve the problem of the cup having some “holes” where the heat can just leak out of the cup.
So, we decided to use our hands to cover the leaks when the hot water was in the cup =)
C- the heat stays in the cup longer when there is more cotton around.
E- the more things trapping the heat IN, the longer the heat lasts.
R- For example, you sleep with a blanket covering you to keep yourself warm, right? The warmness depends on the thickness of the blanket, the thicker the warmer.
I am proud of the fact that the cup experiment went well.
Next time I would try to cover as many leaks
