in school, we are doing a project on heat insulatorsWithin a paper house model, our teacher will place a beaker of HOT waterUsing common materials, we need to keep the water in the beaker as hot as possibleThe water that stays hot the longest will win the competition/projectI REALLY WANT TO WIN!!!!!!!!!!! So far, I only know that i should use bubble wrapWhat else should i use? THANKS SO MUCH :D It is much appreciated.

Answer:

there is a reason that disposable coffee cups are made of styrofoam a layer of styrofoam with aluminum foil on the heat side (to contain radiant heat) is your best bet the thicker the insulation (styrofoam), the better the containment
