M&M vs the Earth

Believe it or not, a pretzel M&M can be used as a great example of the earth. The outside color part of the M&M represents the earth's crust. The second layer of the M&M (the yummy chocolate part) represents the earth's mantle. The inside of the M&M contains a round pretzel that can be used to represent the earth's core. Who knew a model of the earth could be so yummy?
