Melt-Proof Container

We can keep it cold.

The materials needed for this project is Aluminum Foil, Straws, Felt, Tape, Small Plate, and rocks. Others may have used different materials this is just what we choose from the given list. The first thing we did was take the plate and a foundation with the straws so the aluminum foil is supported by something. With the frozen bottle we wrapped it in aluminum foil so the heat will reflect off of it. At the top of the bottle we first put aluminum foil the felt then after that there is another layer of aluminum. Then we put rocks around the bottle because they are good insulators. At the end of the day the total cost was $9.52. The first four hours it was frozen. But the next day it melted.
