Hi! So I really need help with a science project that is due on Thursday. Basically, the teacher will first be putting boiling hot water to see who can keep the hottest temperature and then an ice cube to see who can keep it "alive" for the longest time, I think she will be keeping each for 15 minutes. So basically we have to make an insulator. My idea is to wrap a Styrofoam cup in aluminum foil and then insert that cup into another styrofoam cup and cover the top part with Silicone caulking. PLEASE HELP MEEEE Much appreciation, Cookie Monster
