  • A piece of waxed paper
  • Frosting or peanut butter
  • Two graham crackers
  1. Cut off a large sheet of waxed paper.
  2. Cover it with a layer of frosting or peanut butter.
  3. Take the two graham crackers and place them side by side. Do not leave a space in between.
  4. Slowly pull them apart. You should see the frosting or peanut butter come up slightly in the space. That is like seafloor spreading.
  5. Now remove one of the crackers and wet it slightly. Put it back on the layer of frosting or peanut butter.
  6. Push the two graham crackers together hard. Does one lift up and create a sort of mountain? That is similar to how mountains are formed from the collision of two plates.
