Here are the steps to demonstrate a transform boundary using the snack tectonics materials: 1. Place a small amount of icing along the edge of one piece of wax paper to represent the plate boundary. 2. Hold the two pieces of wax paper next to each other with the icing in between. 3. Slowly slide the pieces of wax paper past each other along the icing, which represents the plates moving horizontally in opposite directions. This demonstrates how transform boundaries form as the plates slide past each other laterally without either plate subducting under the other. The icing represents the fault line where energy is released through earthquakes as the plates shear and grind against each other.
